<br><!----------------------------------------------------------------->
<li>January 3, 2016:
	Version 2.4 with JSmol/signed Jmol version 14.4.1 update 2015.12.23.

<center>
<div style="background: #d0ffe0;border: 1px;width: 80%;">
<big>Version 2.4 provides updates and bug fixes, especially related to ConSurf.
</big>
</div></center>

<ol>
<b>Improved</b>
<li>Clicking on an atom now reports the chemical element in addition to the atom ID.
The element was previously reported in the hover message.

<li>When <b>slab</b> is on, dragging at the right edge of Jmol no longer moves the slab plane.
It has been restored to zooming as usual. A new gesture, Alt+Shift+drag up/down,
now moves the entire slab towards or away from the viewer.

<li>The help for the water toggle button now adds &quot;Protein crystals are highly hydrated,
ranging from about 30% to 70% water in different crystals.&quot; The <i>More..</i> link
there provides literature citations.

<li>Triple clicking seems to be needed for distance/angle measurements (only when using Java).
The Tools tab Distances/Angles help now mentions this.

<li>The documentation for
<a href="notes.htm#aanames"
target="_blank">one-letter codes for amino acids</a>
is more detailed and a reference is cited.


<br><br>
<b>Updated:</b>
<li>The most popular browsers have been re-tested in Windows 7, XP, and OS X, and 
<a href="notes.htm#browsers"
target="_blank">browser compatibility information</a> has been updated. Notably, Google Chrome
no longer supports Java, and the new Edge browser in Windows 10 does not support Java.
Also, a change in Chrome 47, December 2015, caused JSmol to be unable to rotate molecules until
Bob Hanson made a compensating change in JSmol. Finally, the Maxthon browser has been included.
All tested browsers can now be spoofed. Spoofing simply causes FirstGlance to show the relevant
recommendations -- it does not cause the browser being used to emulate another browser.

The visitor counter had been courtesy Sitemeter.Com since February 8, 2006,
recording 583,670 visitors (approximately 1.3 million page views).
Due to problems with Sitemeter, the counter was changed to
StatCounter.Com, setting the initial count to the final Sitemeter count. This change was
made online in the previously released FirstGlance 2.32 on November 12, 2015.

<br><br>
<b>ConSurf related Bugs fixed:</b>
<li>The <i>Backbone</i>, <i>Cartoon</i> and <i>Spacefill</i>
buttons in the ConSurf control panel did not
restore ConSurf colors after they were changed in the FirstGlance control panel.
<li>The <i>Backbone</i>, <i>Cartoon</i> and <i>Spacefill</i>
buttons in the ConSurf control panel did not
hide water that may have been displayed in the FirstGlance control panel.
<li>The <i>Backbone</i> and <i>Cartoon</i> buttons in the ConSurf control panel did not
turn off all renderings that might have been used in the FirstGlance control panel (e.g.
secondary structure rockets or traces).
<li>The <i>Reset</i> button in the ConSurf control panel did not restore the gray
color of backbones of chains not colored by evolutionary conservation.
<li>The 4 views were displaying unwanted water due to remediation in the Protein Data Bank
which assigned chain names to water.
<li>ConSurf was reporting sequence identity between some non-identical chains (e.g. chains A
and P in 2vaa).
<li>When <i>Sequence Numbers</i> or <i>Residue Names</i> were checked, in most Views, they were
colored by chain rather than by the color scheme of the View (e.g. N->C Rainbow).
<li>The <i>ConSurf Colors</i> checkbox was inappropriately greyed out for some Views
(e.g. Thin Backbone).
<li>The <i>ConSurf Colors</i> checkbox was inappropriately greyed out when 
<i>Sequence Numbers</i> or <i>Residue Names</i> checkboxes were used.

<li>The <i>Isolate</i> tool in the FirstGlance control panel was turning off ConSurf coloring.
<li>Dots in view 3 remained yellow after view 2.
<li>Toggling the <i>Spin, Background</i> or <i>Quality</i> buttons in the ConSurf control panel
did not propagate those button states to the Molecule Information Tab or the Tools Tab in the
FirstGlance Control Panel.
<li>Dots were not being shown around the balls and sticks of ligands.

<br><br>
<b>Other Bugs fixed:</b>
<li>With certain large molecules (for example, 7ahl), in JSmol,
Firefox would freeze for about one minute
when the first operation was requested in FirstGlance (for example, toggle spinning off).
Thanks to Bob Hanson for fixing this bug in JSmol!

<li><i>Center visible moieties</i> in the <i>Hide..</i> dialog was broken in FirstGlance
version 2.2.

</ol>

<br><!----------------------------------------------------------------->
<li>October 19, 2015:
	Version 2.32 with signed Jmol/JSmol version 14.4.0 update October 17, 2015.

<br>
<b>Bugs fixed:</b>
<li>
The certificate for the Jmol Java applet was inadvertantly revoked on October 15, 2015,
causing operation of all earlier versions to be denied.
</li>
<li>
In JSmol (HTML5, no Java) the <b>JSmol menu</b> could not be opened by clicking on the frank or
right-clicking in JSmol. This longstanding bug has been fixed thanks to Bob Hanson.
</li>
<li>
In the help for <i>Sequences</i>, the links to Uniprot sequences stopped going directly
to the sequences section (due to a change at Uniprot).
</li>
</ol>


<br><!----------------------------------------------------------------->
<li>September 5, 2015:
	Version 2.31 with signed Jmol/JSmol version 14.3.7_2014.09.20.
<ol><li>
The Google Chrome browser stopped supporting Java on September 1, 2015. This release
of FirstGlance intercepts a request to use Java in Chrome, suggesting that you use a different
browser (Internet Explorer, Firefox and Safari all support Java), or use FirstGlance
without Java.
</li></ol>


<br><!----------------------------------------------------------------->
<li>June 16, 2015:
	Version 2.3 with signed Jmol/JSmol version 14.3.7_2014.09.20.

<ol>
<b>New:</b>
<img src="imgs/seqnumresnam.jpg" align="right" border="1" hspace="8">
<li>Sequence numbers and residue names can now be displayed for all residues. New checkboxes
are located at the bottoms of the Molecule Information Tab, Views Tab, and Tools Tab, just
below the Labels (S-, X, ?) checkboxes.

<li>An index to all the capabilities of FirstGlance, and where to find them, has been created:
<a href="where.htm" target="_blank">Where? How?</a> is linked at the bottom of every tab
except Preferences, and underneath the molecule.

<li>A new <i>Practical Guide to Homology Modeling</i>, which also tells how to find X-ray or NMR
models, is now linked to the first page at FirstGlance.Jmol.Org, and in the Resources tab.

<br><br>

<b>Bugs fixed:</b>

<li>Putting halos on some atoms (with <i>Find..</i>) caused the automatic centering to fail
when using <i>Isolate..</i>.

<li>Under <i>Sequences</i> (Molecule Information Tab) the link to
PDBe (Europe) has been removed. The PDBe website was restructured and the interactive
sequence display seems no longer to be available.

<li><i>Reset</i> was not resetting the Labels checkboxes (bottom of every tab except Preferences).

<li><i>Crystal Contacts</i> (<i>Tools</i> tab) was not showing any balls for contacting nucleotides that lacked
a phosphorus atom (5' terminal nucleotides). The c5' atoms of those nucleotides are now shown
as balls. For example, 14 nucleotides contact the asymmetric unit of 1d66.
12 of those have phosphorus atoms; 2 lack phosphorus atoms. Prior to the bug fix, only 12
nucleotide balls were shown.

</ol>

<br><!----------------------------------------------------------------->
<li>September 22, 2014:
	Version 2.2 with signed Jmol/JSmol version 14.3.7_2014.09.20.

<ol>
<b>New:</b>

<img src="imgs/isolate.jpg" align="right" border="1" hspace="8" vspace="8">
<li>A new dialog, <i>Isolate</i>, will be found between the previously
available <i>Hide</i> and <i>Find</i> (near the bottoms of the first
three tabs). <i>Isolate</i> makes it easy
to hide everything except one entity.
<i>Isolate</i> can be used in combination with <i>Hide</i>, in either
order.

<li><img src="imgs/channel.png">Molecular animations are
<a href="ppt/polyview-3d-examples.ppt"
target="_blank">demonstrated in Powerpoint</a>&reg;.
These animations for Powerpoint were generated with the PolyView-3D Server
recommended in
<a href="slides.htm"
target="_blank">Presenting Views from FirstGlance</a>, which can be
accessed from a link at the bottom of the lower left panel in FirstGlance.

<br><br>
<b>Improved:</b>

<li><i>Hide</i> can now hide atoms with halos (namely, atoms that were
given halos with <i>Find</i>).
This is useful when multiple copies of the same thing need to be hidden.
For example, 1or9 is an 18-chain assembly. (Use Java for this large
structure.) Each chain has a helical domain
and a globular domain. To hide all 18 globular domains, <i>Find</i> sequence range
"61-199". Then <i>Hide</i> atoms with halos.

<li><i>Hide</i> now informs you when you try to hide something that is
not present in the model. (Previously, it said nothing while the molecular view
remained unchanged.)

<li>The term <i>chain</i> is now linked to an
<a href='http://proteopedia.org/wiki/index.php/Chain'
target='_blank'>explanation</a>.

<li>An 
<a href='http://proteopedia.org/wiki/index.php/Backbone_representations'
target='_blank'>explanation of backbone traces</a> was created in Proteopedia,
and linked wherever backbone traces or ribbons are mentioned.

<li>In the <i>Chain Details</i> help (Molecule Information Tab), individual chains
can now be highlighted by clicking on the chain name.

<li>The <i>Vines</i> view now remembers its checkboxes until the end of a session.

<li>For biological unit models from the MakeMultimer server, the
help was improved for <i>Biological Unit</i> under the <i>Resources</i> tab.

<li>For NMR models, the
help was improved for <i>Local Uncertainty</i> under the <i>Views</i> tab.

<li>The "smaller ligands+" checkbox in the ligands+ button help is now
remembered for the duration of a session.

<li>A change in Jmol long ago has been causing the initial zoom to be too high when Jmol is rectangular. This has been fixed (set zoomLarge false).

<li>Alternate locations are now discussed in the help for the <i>Vines</i> view, where they can best be seen.

<li>The Gallery has some new cases (1ijw, 3hyd and 3if7).

<li>The text in the Snapshot Gallery was updated. The snapshots themselves have not yet been updated.

<br><br>

<b>Bugs fixed:</b>

<li>Centering of the visible atoms often did not work. (Thanks to Bob Hanson for
fixing this bug in Jmol.)

<li>The tool <i>Salt Bridges / Cation-Pi Interactions</i> failed to warn that some interactions
are not shown when relevant amino acids are missing, or have incomplete sidechains. The new
warning has a yellow background.

<li>The <i>Crystal Contacts</i> and <i>Unit Cell</i> tools now behave
appropriately for models that lack crystallographic information,
including homology models from Swiss-Model, biological units from
MakeMultimer, and models from the Orientations of Proteins in Membranes
server.

<li>Homology models from Swiss-Model, when uploaded, generated a large
spurious alert message.

<li>Homology models from Swiss-Model, when uploaded, had a garbled
report in the molecule information tab.

<li>Some models from the Orientations of Proteins in Membranes server
(available in the Resources Tab)
had garbled reports in the molecule information tab, and also
produced a large spurious alert during loading. Example: 4fz0.

<li>Models from the Orientations of Proteins in Membranes server
(available in the Resources Tab) contain pseudo-atoms marking the 
predicted boundaries of the hydrophobic portion of the lipid bilayer.
In the View: Vines, with more detail checked, when the ligands were
hidden with the Ligands+ button, pseudo-atoms close to protein remained
visible as erroneously covalently bonded to protein.

<li>Hide, Atom: when the atom was calcium (e.g. 4aqr) some results
were incorrect.

<li>Reset was resetting most things even when canceled.

<li>Reset was not obeying the spin preference.

<li>Reset was not turning the Quality button off.

<li>The "smaller water" checkbox in the water button help was being
remembered but not being obeyed.

</ol>

<br><!----------------------------------------------------------------->
<li>June 12, 2014:
	Version 2.1 with signed Jmol/JSmol version 14.0.17_2014.06.11.

<ol>

<b>New:</b>

<img src="imgs/preferences.jpg" align="right" border="1">
<li>Preferences:

<ul>
<li>Spinning when the session begins is now optional.

<li>When using JSmol, you can hide the suggestions for browsers
that perform better. Exceptions:

<ul>
<li>Because the performance of Internet
Explorer with JSmol is unacceptably slow, the suggestion not to use it
cannot be hidden.

<li>Because rotation in Opera is unacceptably slow/jerky,
the suggestion not to use it cannot be hidden.

</ul>

<li>When using JSmol, you can hide the recommendation to use Java
for better performance.

</ul>

<br>

<b>Improved:</b>

<li>Help and explanations have been clarified in several places,
especially for <i>Crystal Contacts</i> (<i>Tools</i> tab).
<!-- chain length 'present in the model' / 'including N missing'.
-->

<br><br>

<b>Bugs fixed:</b>

<li>Atoms that were hidden were nevertheless reported when touched with the mouse
(onMouseOver), or clicked. This caused mis-identification of atoms, and
selection or hiding of incorrect moieties with mouse clicks.
(Jmol bug, thanks to Bob Hanson for the fix.)

<li>Water hydrogen atoms were inappropriately displayed when present in
the model (1lcd, 1lfa). 
(Jmol bug, thanks to Bob Hanson for the fix.)

<li>The <i>Contacts & Non-Covalent Interactions</i> Tool was not
working when the PDB file lacked standard header information.
Thus it was not working with uploaded PDB files such as homology models,
biological units from MakeMultimer, etc. Thanks to Eugenia Polverini
(University of Parma, Italy) for calling this bug to my attention.

<li>In the <i>Contacts & Non-Covalent Interactions</i> Tool, selecting
a sequence range starting with the higher sequence number and finishing
with the lower sequence number did not work.

<li>The number of missing residues reported was incorrect when
there are multiple models (e.g. 2q3o). The sum for all models was
reported rather than the number missing in the first model.

<li>The "Get Biological Unit" buttons were going to a submission form
instead of the final result for the current PDB code, due to a change
at the MakeMultimer server.

<li>PDB files lacking SOURCE records caused FirstGlance to fail to load.

<li>Clicking on a water oxygen atom incorrectly identified it as
"(main chain)". This has been fixed for both HOH and DOD (deuterium
oxide).

<li>The amino acids graphic chart was not displayed in the
<a href="notes.htm#labels"
target="_blank">section on amino acids in the Notes</a>.

</ol>

<br><!----------------------------------------------------------------->
<li>April 27, 2014:
	Version 2.00 with signed Jmol/JSmol version 14.0.13.
<center>
<div style="background: #d0ffe0;border: 1px;width: 80%;">
<big>Version 2.00 mostly concerns making the use of
JSmol (no Java, the new default) more user friendly.
</big>
</div></center>


<ol>

<b>New:</b>

<li><b>Default: no Java.</b> This version defaults to using no Java
(using JSmol and HTML5). Because JSmol (no Java) is significantly slower
than Jmol (Java), a "BUSY" message appears over the molecule while
commands are processed.
Jmol (Java) remains an option in
<i>Preferences</i>, or with a checkbox at
<a href="http://firstglance.jmol.org"
target="_blank">FirstGlance.Jmol.Org</a>.

<li><b>Browser advice:</b> The Chrome browser is recommended when
using JSmol because it has the best performance. Internet
Explorer (extremely slow overall) and Opera (very slow rotation)
are discouraged. Recommendations appear in yellow
banners, and can be seen, without installing multiple browsers,
by spoofing a particular browser:
<ul>
<li>
<a href="fg.htm?mol=1d66&spoof=ie"
target="_blank">Spoof Internet Explorer</a>
<li>
<a href="fg.htm?mol=1d66&spoof=opera"
target="_blank">Spoof Opera</a>
<li>
<a href="fg.htm?mol=1d66&spoof=firefox"
target="_blank">Spoof Firefox</a>
</ul>

<li><b>Preference:</b> A new tab <i>Preferences</i> has a checkbox
to set using Java (Jmol_S, the signed Jmol applet) as the default.
Query parameters &JAVA or &NOJAVA override this preference.
The checkbox at FirstGlance.Jmol.Org uses query parameters.

<li><b>Large molecules:</b> When the model contains 10,000 atoms or more,
using Java (Jmol_S, the signed Jmol applet) is recommended for
better performance.

<li><b>Multiple models:</b> When using JSmol (no Java), and when
the data file contains multiple models
(typically for NMR experiments),
only the first model is loaded. This avoids overloading JSmol.
Currently there is no "View All Models" capability when using JSmol, but this
is planned for a future version of <i>FirstGlance</i>. When using the
Jmol_S signed Java applet, all models are loaded, and "View All Models"
is available.

<li>
<a href="java.htm"
target="_blank">Installing and Enabling Java</a>
has been explained in detail for Windows and OS X and all
popular browsers.

<br><br>

<b>Bugs fixed:</b>

<li>The Labels Front checkbox was not working.
<li>Some links to <i>Troubleshooting</i> were broken.

</ol>

<br><!----------------------------------------------------------------->
<li>January 5, 2014:
	Version 1.98 with signed Jmol/JSmol version 14.0.4.

<center>
<div style="background: #a0ffa0;border: 1px;width: 80%;">
<big>Version 1.98 is a major upgrade: the Jmol Java applet
is now always signed. Optionally, FirstGlance will run
without Java using JSmol.</big>
</div></center>

<ol>

<b>New:</b>

<li><b>Signed Java Applet.</b>
This version defaults to the signed Jmol applet. This was
done because Oracle has announced that unsigned
<a href="java.htm"
target="_blank">Java</a>
applets will soon
be prohibited for security reasons.

<li><b>Without Java.</b>
This version can also operate with
<a href="notes.htm#jsmol"
target="_blank">JSmol</a>,
instead of the Jmol Java applet.
JSmol does not require Java, which has become increasingly
problematic. (The JS in JSmol stands for javascript.)
Performance (smoothness of rotation, speed of responses)
is somewhat diminished in JSmol, but adequate except for the largest
structures (thousands of atoms).

<br>

<b>Bugs fixed:</b>

<li>"Center visible chains" was not always working.

<li>Some hydrogen atoms, and one nitrogen in histidine, were not being
colored in the <i>Charge</i> view. (Protein amino terminal charges are
still not shown due to difficulty in identifying them.)

<li>When a standard residue occurs as a ligand, the count reported
in the <i>Molecule Information Tab</i> included occurrences in protein
or nucleic acid, not just ligand (e.g GLY in 3f4j, 4cpa; A in 1bkx).

<br>
<b>OCA:</b>
<li>Uses of OCA removed in version 1.95 have been restored.

</ol>

<br><!----------------------------------------------------------------->
<li>July 7, 2013:
	Version 1.951 with Jmol applet version 13.0.15.
<ol>
<li>The signed Jmol applet is used for Mac OS 10.6 (Snow Leopard),
Mac OS 10.5 (Leopard), and Mac OS 10.4 (Tiger). This works around
what appears to be a bug in Java version 1.6.0_51. This change
does not affect Windows or Mac OS 10.7 or later, which use Jave 1.7.
</ol>

<br><!----------------------------------------------------------------->
<li>June 16, 2013:
	Version 1.95 with Jmol applet version 13.0.15.
<ol>
<b>New:</b>
<li>Two new Tools, <i>Crystal Contacts</i> and <i>Unit Cell</i>,
have been added. Further options for these views are planned, but the
basic views appear to be working.

<li>A new View, <i>Solid</i>, has been added. It is the same as the
initial view in the tool <i>Contacts & Non-Covalent Interactions</i>,
but with a new explanation and examples.

<li>The molecule information tab now has a line about the presence
or absence of hydrogen atoms in the model. It is linked to a new
help panel with details, and an introduction to hydrogen atoms in PDB files.

<br><b>Enhanced:</b>

<li><i>Hydrophobic/Polar</i> (Views tab) was improved. Cys is now
deemed hydrophobic. Most importantly, non-standard amino acids are colored
white (formerly magenta).

<li>Local Uncertainty (Views tab) now gives the minimum, average, and
maximum temperature for each chain, water, ligands+, and hydrogen.
The chain with the lowest average temperature among
a group of sequence-identical chains is highlighted in boldface.

<li>Slab now has a 20% thickness option, as well as the previously
available 10%, 6%, and 3%. Also there is a new checkbox which unhides
the back of the molecule, so you can see the inside of a cavity or
channel.

<li>The report by <i>Disulfides/S/Se</i> is more detailed and includes
a count of sulfur in non-standard residues. There are also many more
examples listed in the help.

<li>Instructions for obtaining Biological Units now offer a <i>backbone
only</i> model, useful when the all-atom model exceeds Java memory.

<br>

<b>Bugs fixed:</b>

<li>Some buttons (such as Spin and Background) were sometimes inappropriately
canceling centering, hiding, or target selection in <i>Contacts</i>.

<li>Non-standard amino acids were being colored "polar" (magenta) in the
<i>Hydrophobic/Polar</i> view. They are now white.

<li>Some selenocysteines were not being counted by <i>Disulfides/S/Se</i>.

<li>Selenium and iron (Se, Fe), when clicked, were being inappropriately
described as "Epsilon, 5th".

<li>OCA has been out of service for weeks, so some links that use OCA
have been removed or directed to other services. Removed: FASTA sequences,
OCA under Resources. Redirected: View PDB file now fetches from RCSB.

</ol>

<br><!----------------------------------------------------------------->
<li>May 5, 2013:
	Version 1.92 with Jmol applet version 13.0.13.
<ol>
<b>Additions:</b>
<li>The <i>Hide..</i> and <i>Find..</i> tools are now available in all
four tabs (at the bottom). Thanks to Frieda Reichsman for this suggestion.

<li><i>Secondary Structure</i> (Views tab) now reports the percentages
of helix, strand, and neither.

<li><i>Charge</i> (Views tab) now reports the numbers of
positively and negatively charged amino
acids with incomplete sidechains, in addition to the total numbers.
The counts now exclude hidden residues and
alternate locations and include the carboxy termini.
Previously carboxy termini were overlooked in the Charge view,
but now they are colored red for negative charge.
(Amino termini are more complicated and will be added in a later version.)

<li>Atoms with <b>alternate locations</b>, when they occur, are
now reported in the <i>Molecule Information Tab</i>, with a tool
to find them. Examples: 3hyd, 1bsz.

<br>

<b>Changes:</b>
<li>The initial background is black instead of white, to make the "empty
baskets" for missing residues more visible.
<li>The Spin, Background, etc. buttons have been rearranged to make them
more consistent between tabs.

<br>
<b>Bugs fixed:</b>
<li>Hide and Find were missing from the molecule tab when the molecule
lacks a proper PDB file header (such as PDB files from MakeMultimer
or Orientations of Proteins in Membranes).
</ol>

<br><!----------------------------------------------------------------->
<li>April 23, 2013:
	Version 1.9 with Jmol applet version 13.0.13.
<center>
<div style="background: #a0ffa0;border: 1px;width: 80%;">
<big>Version 1.9 is a major upgrade of <i>FirstGlance in Jmol</i>.</big>
</div></center>
<ol>
<li>Controls have been reorganized into 4 sections, each with its own tab:
Molecule, Views, Tools, and Resources.

<li><img src="empty-basket.png" align="right">
The initial view now marks regions with missing residues
with an "empty basket" (see image at right). The empty baskets
can be hidden with a checkbox in the <i>Missing Residues</i> report,
available from a link the Molecule Tab.

<li>The molecule tab (titled with the PDB code when applicable) offers
information from the "header" of the PDB file:
	<ol type="a">
	<li><b>Name</b> of the molecule.
	<li><b>Dates</b> of deposition and release.
	<li><b>Method</b> of structure determination.

by <i>FirstGlance</i> to help novices interpret these values.
	<li>Asymmetric unit:
		<ol type="i">
		<li>The <b>number of chains</b>, and the number of sequence-distinct chains.
Clickable chain names identify the location of each chain.
		<li>Details about each chain including its <b>length, whether protein,
DNA or RNA, presence of non-standard residues</b>.
		<li><b>Sequences</b> are easily accessible from links to various sequence databases.
(There is still no clickable sequence-to-structure listing -- it remains
under development.)

		<li>The total number of <b>missing residues</b>. Also a
summary table listing the residues missing in each chain, and
their sequence numbers, and the number of charged residues that
are missing. (The S2C "gaps" server is no longer necessary.)

		</ol>
	<li>The <b>biological unit</b> is readily accessible.
	<li><b>Ligands and non-standard residues</b> are listed with their
<b>counts and full names</b>. Clicking on one shows its position(s) in the model.
	<li>The publication <b>abstract</b> at PubMed is one click away.
	<li>All literature citations given in the PDB file are listed, with
clickable PubMed ID and DOI links.
	<li>The PDB file text is one click away.
	</ol>
<li>The <i>Views Tab</i> offers display and color schemes that affect
the entire structure. It includes the 8 views previously available, plus
Local Uncertainty (formerly under <i>More Views</i>) with expanded help and
options.

<li>The <i>Tools Tab</i> offers tools that identify, highlight, or measure
specific substructures: Disulfides/S/Se, Salt Bridges/Cation-Pi, Contacts,
Distances/Angles, and Advanced/Technical. None of these are
completely new but there are some new options and expanded explanations.

<li>The <i>Resources Tab</i> offers guidance for use of servers external
to <i>FirstGlance</i>, some of which were formerly available
under "Key Resources". Guidance has been greatly expanded. In addition
to the previously featured resources (biological unit, evolutionary conservation,
and Proteopedia), there is now guidance for all-atom clash analysis with
MolProbity, prediction of intrinsically unstructured regions of protein
chains, and marking of lipid bilayer boundaries for integral membrane
proteins.

<li><b>Hide..</b> and <b>Find..</b> are now available at the bottoms of any
of the four tabbed control panels. There are some new capabilities in these
tools:

	<ol type="a">
	<li>The Find.. tool now finds amino acid or nucleotide sequence fragments,
e.g. <b>sequence=skek</b> or <b>sequence=cgg</b>.
	<li>The Hide.. tool now asks whether you wish to hide all copies
of the residue/group or atom you clicked, or only the single one clicked.
	</ol>

<li>Formerly, <i>FirstGlance</i> showed structures but did not
report counts. This version, for the first time, <b>reports counts</b>,
e.g. number of chains, amino acids and nucleotides,
missing residues, ligand groups, non-standard residues,
disulfide bonds, sulfur
atoms, selenium atoms (selenomethoinine and selenocysteine), positive
and negative charges, and numbers of
atoms/residues found with the <i>Find..</i> tool.

<li>Bugs fixed:
	<ul>
	<li>In the <i>Hide..</i> tool, with the range option, formerly when the
higher sequence number was clicked first, hiding failed.
	<li>In the <i>Hide..</i> tool, with the Atom option, the red list of
atoms hidden
inadvertantly included the XYZ coordinates of the atom (evidently due
to a change in Jmol). Also clicking the same atom twice (possible even after
it is "hidden" in some displays) was not properly handled.
	<li>In the <i>Find..</i> tool, there were problems when the query
included a single quote, as in *.c5'.
	<li>The <i>Backbones</i> checkbox in <i>Contacts Shown</i> was not
being remembered.
	</ul>

</ol>
<br><!----------------------------------------------------------------->
<li>February 13, 2013:
	Version 1.47 with Jmol applet version 12.2.34.
<ol>
<li>Operation in the <b>Internet Explorer 9</b> web browser has been restored
after failing for several months. (Operation in Internet Explorer 7 and 8,
Firefox and Chrome never failed.)
Operation in IE9 was accomplished with the following restructuring:
	<ul>
	<li>FirstGlance now uses Jmol.js for the first time.
	<li>The division layout (file fg.htm) was restructured following the
<a href="http://biomodel.uah.es/Jmol/resizable/inicio.htm"
target="_blank">resizable Jmol scheme</a>
kindly provided by
<a href="http://biomodel.uah.es/personal/inicio.htm"
target="_blank">Angel Herr&aacute;ez</a>.
	</ul>

<li>
<a href="java.htm"
target="_blank">Java security risks and recommendations for using Java safely
have been documented</a>.

<li>
Zoom help was expanded to include moving the cursor to the right inside
edge of Jmol. Mac: <img src='zoom-cursor.jpg' align='center'>; Windows:
<img src='zoom-cursor-win.jpg' align='center'>.

<li>A link to <i>Mouse Use</i> was added beneath Jmol, along with a link
to <i>Java Security</i>.

<li>Updated list of
<a href="help.htm?makeTroubleHelp%28%29"
target="_blank">compatible browsers</a>
and notes on
<a href="notes.htm#safari"
target="_blank">browser peculiarities</a>.

</ol>
<br><!----------------------------------------------------------------->
<li>June 17, 2012:
	Version 1.46 with Jmol applet version 12.2.30.
<ol>
<li>The cutoff distance for van der Waals interactions in the <i>Contacts</i> display
has been reduced from 4.5 &Aring; to 4.0 &Aring; at the recommendation of several
crystallographers. See <a href="notes.htm#hphob" target="_blank">Van der Waals interactions</a>.

<li>Using <i>Advanced Options</i> (at
<a href="http://firstglance.jmol.org" target="_blank">firstglance.jmol.org</a>,
or by clicking <i>New Session</i> within an existing session)
you can request the <b>signed Jmol applet</b>. This
version of Jmol's signed applet enables <b>writing a .jmol file that contains
everything (including the state script and the atomic coordinates) needed
to regenerate the view</b> at the time the .jmol file was written. The .jmol
file can be dragged into the Jmol application, or the signed applet. To
write a .jmol file, click on <i>Jmol</i> at the lower right of the molecule
to open Jmol's menu, then open the Console. In the lower white box,
issue the command "write filename.jmol".

</ol>
<br><!----------------------------------------------------------------->
<li>Minor Interim Upgrades (dates noted below):
<ol>
<li>
<a href="notes.htm??mol=1hho#pqs"
target="_blank">Options for visualizing <i>Biological Assemblies</i></a>
have been expanded to include
the <i>MakeMultimer Server</i>, and to caution about the frequent apparent
errors at the PISA server. (These changes were added to version
1.45 on May 7, 2010.)

<li>Added a color key to <i>Color by Uncertainty</i> (under
<i>More Views..</i>).

<li>In <i>Contacts..</i>, added a caution that salt bridges and
cation-pi interactions are shown only for protein.

<li>A method for calculating pI and charge at various pH values was
<a href="notes.htm#charge"
target="_blank">documented</a>, and linked into the <i>Charge..</i>
dialog. (This and the previous two changes were added to version 1.45 in May/June, 2011.)

<li>Added more information under "How Does It Work?" in
<a href="whatis.htm"
target="_blank">What Is FirstGlance in Jmol?</a>.

<li>Noted in
<a href="adoption.htm"
target="_blank">Adoptions</a> that <i>Nature</i> discontinued direct <i>3D
View</i> links to FirstGlance as of the September 23, 2010 issue.
(This and the previous item were added to version 1.45 in February, 2012.)

</ol>

<br><!----------------------------------------------------------------->
<li>April 14, 2010:
	Version 1.45 with Jmol applet version 11.8.22.
<ol>
<li>Under <i>More Views..</i> is a new dialog to show disulfide bonds
clearly, as well as to show cysteine residues not participating in
disulfide bonds. Also cys residues can be labeled.

<li>Under <i>Key Resources..</i> PQS (Probable Quaternary Structure) has
been updated to use PISA, as well as offering PQS and RCSB for obtaining
biological assemblies.

<li>Some progress was made in preparation for
<a href="languages/tplans.htm"
target="_blank">translation to other languages</a>,
but FirstGlance is still not translation-ready.

</ol>
<br><!----------------------------------------------------------------->
<li>February 4, 2010:
	Version 1.44 with Jmol applet version 11.8.17.
<ol>
<li>Jmol now <b>resizes automatically</b> with the browser window.

<li><b>Added <i>Key External Resources</i></b>, replacing the 4 buttons "PQS, PDB,
OCA, Gaps?". New on the list are Proteopedia, Evolutionary Conservation,
and MolProbity.

<li><b>Changed <i>Secondary Structure</i>.</b> It now represents beta
strands and sheets in a more realistic fashion -- gone are the straight planks
shown in earlier versions. Also the ribbons are a bit narrower in <i>Cartoon</i>.

<li>The initial view for <b>Charge..</b> is now to color only the charged
atoms. All the previous options remain available.

<li>Status HPUB at the PDB, or an invalid PDB code, is detected, and
explanatory help should appear automatically. (A similar feature was
present in version 1.02, but was later broken by changes at the PDB,
and regardless, had not been installed in versions higher than 1.1.)

<li>Incorporated links to
<a href="http://proteopedia.org"
target="_blank">Proteopedia.Org</a> in several places, with explanations
of why it is useful in a particular context.

<li>Limitation removed: Atoms can now be <b>identified with Slab on</b>,
due to improvements in Jmol. Identification is by clicking on the atom
(which reports at the lower left of Jmol) or by touching the atom,
which reports in a yellow "hover" box. Slab mode can also be used in the
Contacts and Hide dialogs now.

<li>Protein atom identifications now include "main chain" or, for sidechain
atoms, the greek
letter, spelled out in English.

<li>Included "Atom" in hover report (e.g. "...Element=C, Atom=C7").
It was previously included in the identification report produced by
clicking on an atom.

<li>The extensive
<a href="notes.htm"
target="_blank">Notes</a> document was updated
throughout. Some more technical documents have not yet been updated,
but are marked as out of date (e.g. those
<a href="about.htm"
target="_blank">listed</a>
under <i>Technical Information for Programmers</i>).

<li>Bug fixed: thymidines were erroneously labeled as having
incomplete sidechains "S-" due to a change in nomenclature
with the remediated PDB format (t.c5m is now t.c7).

<li>Bug fixed: A351 in 1bkx is not covalently bonded to any other
nucleotide. It was not displayed within the "ligands+" group as intended.

<li>Bug fixed (I think): FirstGlance occasionally failed to complete
loading. This was found to happen when the server supplying the visitor
count (sitemeter.com) failed to respond. The meter code was put inside
a division, which appeared to permit loading even without a response.

<li>Bug in Jmol fixed: in "Center Atom" mode, clicking on Jmol's
background no longer causes a zoom out.

<li>Bug in Jmol fixed: hydrogens on charged sidechain nitrogens are
now colored blue in the Charge.. display, "color only charged atoms".
Formerly they were white.

<li>
<a href="adoption.htm"
target="_blank">Adoptions</a> was updated to include <i>Protein Science</i>.

<li>Work was begun to prepare <i>FirstGlance in Jmol</i> for translation to
<a href="languages/es/index.htm"
target="_blank">espa&ntilde;ol</a>
and other languages.

</ol>
<br><!----------------------------------------------------------------->
<li>April-December, 2008:
	Version 1.40-1.42 with Jmol applet version 11.5.20.
	<br>
	Limited release for the Epitopia server.
<ol>

<li>Added graphics <b>Quality</b> toggle button.
<li>Added support for the
<a href="http://epitopia.tau.ac.il"
target="_blank"><b>Epitopia</b> Server</a>.

<li>The <a href="adoption.htm"
target="_blank">Adoptions</a> page was updated to include Proteopedia
and TOPSAN.

<li>Updated help for taking
<a href="slides.htm"
target="_blank">snapshots for presentations</a>.

</ol>

<br><!----------------------------------------------------------------->
<li>September 15, 2007:
	Versions 1.39 (for OCA and ConSurf/Pepitope/Selecton with Jmol applet
	11.3.11)
	<br>
	and version 1.01 (at firstglance.jmol.org, Jmol applet remains 10.2.0).
<ol>

<li>Fixed a bug that prevented hiding (in <i>Hide..</i>)
or selecting (in <i>Contacts..</i>)
chains of DNA. This bug was created when the Protein Data Bank changed
the PDB format on August 1, 2007, in accord with their data remediation project.
Specifically, the former nucleotide names A,C,G,I,T,U now designate only
RNA, while DNA nucleotides are named DA,DC,DG,DI,DT,DU.

<li>Fixed a bug that prevented the Labels: Front checkbox from
working. This had resulted from a change in Jmol. (This fix applied only
to version 1.39.)

<!--
Aside from version.htm and top.js (version number), the only change
was in isStdNucleotide() in jcontrol.js.
-->

</ol>

<br><!----------------------------------------------------------------->
<li>Limited Releases*, April-August 2007: Versions 1.36-1.38.

<ol>

<li>Support for the 
<a href="http://pepitope.tau.ac.il"
target="_blank"><b>Pepitope</b> Server</a>.

<li>Support for the 
<a href="http://selecton.bioinfo.tau.ac.il"
target="_blank"><b>Selecton</b> Server</a>.

<li>*Version 1.36 [April 7, Jmol 11.1.27] and 1.37 [April 13, Jmol 11.1.27]
were installed at only the Pepitope and Selecton servers. Version
1.0 (Jmol 10.2.0) remained installed at firstglance.jmol.org, and version
1.2 (mislabeled 0.995, Jmol 10.2.0) remained at ConSurf and OCA.

<li>* Version 1.38 [August 27, Jmol 11.3.11] was installed for Pepitope, Selecton,
and at the OCA server (used for
<a href="notes.htm#uploads"
target="_blank">uploading</a>
PDB files saved from Pepitope or Selecton jobs). Version 1.0
(Jmol 10.2.0) remained installed at firstglance.jmol.org.

<li>In Jmol 10.2.0, calcium was incorrectly classified as protein.
This bug was fixed in later Jmols, enabling the removal of the workaround in
FirstGlance that was needed previously.

<li>Preliminary support for submitting a Jmol state script to generate
<b>high-resolution images</b> at the <b>ConSurf Server only</b>.

<li>Added Polyview-3D to
<a href="slides.htm"
target="_blank">Presenting Molecular Views</a>. (August 6, 2007)

</ol>

<br><!----------------------------------------------------------------->
<li>December 10, 2006 - January 14, 2007:
	Version 1.0 (with Jmol applet version 10.2.0).
<ol>

<li>Dec. 10: After seven months of service, no major problems came to light in version <b>0.991</b>,
so I deemed it version <b>1.0</b> with no further changes. Version 1.0 remains
the main public version at this time.

<li>Jan. 14: Added

<a href="whatis.htm"
target="_blank">What Is FirstGlance in Jmol?</a> (Thanks to Phil Leader
for suggesting this.)

<li>Jan 14: Added
<a href="slides.htm" target="_blank">instructions</a>
for copying <b>static snapshots</b> of molecular views
and pasting them into presentations or documents. Also mentioned
MolSlides in Jmol. The new instructions
are linked to the bottom of every help panel.

<li>Since version 0.991 is now version 1.0, version <b>0.995</b> should have
been called version <b>1.2</b>.

<li>Version 0.995 (1.2) is public, at this time, only at the ConSurf Server
and OCA. (The version at OCA was updated to 0.995 to support upload of
saved ConSurf job PDB files.)


</ol>

</ol>
<br><!----------------------------------------------------------------->
<li>August 23 - September 3, 2006: Version 0.995 (with Jmol applet version 10.2.0).

<ol>

<li>This version was <b>released at the ConSurf Server and OCA Servers only</b>. It was
not released at firstglance.jmol.org pending further improvements.
Release at the OCA Server was to support display of saved and uploaded
ConSurf PDB files.

<li> Added support to display evolutionary conservation results
from the <a href="http://consurf.tau.ac.il"><b>ConSurf Server</b></a>.
<ul><small>
<li>Support for ConSurf increased the size of <i>FirstGlance</i> by
about 25% (from 15K lines in .htm and .js files to 20K). Most of the
code was adapted from <i>Protein Explorer</i>.
<a href="consurf/cs_in_fg.htm" target=_blank>More..</a>
<li>This involved the first use of messageCallback from Jmol to javascript,
which enabled the following change, and will enable future enhancements.
</small></ul>

<li> The "Please Be Patient!" help that appears at the beginning of a session
is now <b>automatically replaced</b> with the <i>Introduction</i> after the
molecule appears.

<li> Moved the visitor count from the "Please Be Patient!" help (which
now may disappear so quickly the count might fail to load)
to beneath the molecular view (scroll down).

<li> Added a new link to the control panel: <i><b>New Session</b></i>.

<li> The <i><b>Charge..</b></i> default <b>color scheme</b> has been changed to make it
easier to see the distribution of charged atoms. The old 5-color scheme
remains available via a checkbox.

<li> One of the new <i>Charge..</i> views shows only charged atoms. Because
some crystallographic models have <b>incomplete sidechains</b>, where the charged
atoms are missing, these are detected and indicated.

<li> <i>Hide..</i> has a new option to hide a <b>range of
residues</b> within one chain (or multiple such instances). This
is similar to the range-targeting function previously available
in <i>Contacts</i>.

<li> <i>Hide..</i> has a new <i><b>Invert Hiding</b></i> checkbox. 
Previously hidden moieties are displayed, and vice versa.
This makes it easier, for example,
to view a single chain out of many (first hide it, then
invert hiding).

<li> Added instructions for copying <b>static snapshots</b> of molecular views
and pasting them into presentations or documents. The new instructions
are linked to the bottom of every help panel.

<li> Bug fixed: In <i>Hide..</i>, the option to <i>Center Visible Chain</i>
was not working reliably.

<li> Bug fixed: Following a <i>Reset</i>, certain operations (such as
<i>Center Visible Chains</i>
in <i>Hide..</i>) had inappropriate consequences
(such as an inappropriate start of spinning, or failure to center properly).

<li> Bug fixed: After showing <i>Contacts</i>, and then using
<i>Center Atom..</i>, clicking <i>Return to Contacts</i> failed to
clear centering mode.

<li> Bug fixed: Jmol defaults to showing hydrogen bonds for rare
PDB files. These are now hidden with an explicit "hbonds off".
An example is 4MDH (in
<a href="http://bioinformatics.org/firstglance">
FGiJ 0.991</a>). See <a href="bugsjmol.htm">Jmol Bugs</a>.

<li> Clicking the "Zoom Up" button no longer intereferes with target
selection for Contacts, and does not interfere with hiding a range of residues,
by displaying its help.

<li> Added a color key for the element-colored displays of salt bridges
and cation-pi interactions (under <i>More Views..</i>).

<li> Added the journal <i>Molecular Biosciences</i> to the
<a href="adoption.htm" target=_blank>Adoptions</a> page.



</ol>
<br><!----------------------------------------------------------------->
<li>May 10, 2006: Version 0.991 (with Jmol applet version 10.2.0).
<ol>

<li> <a href="notes.htm#nsr" target=_blank>Non-standard residues</a>
are now shown as crosses ("stars" in Jmol command language) by default. The crosses can be hidden
in <i>More Views..</i>, or <i>Ligands+</i>. This change was made
in accord with the goal of not leaving important information invisible.
Crosses were chosen because they don't distract too much from the backbone
displays when there are many non-standard residues, as for 1EVV.
Examples:
<a href="fg.htm?mol=1evv" target=_blank>1EVV</a>,
<a href="fg.htm?mol=1bkx" target=_blank>1BKX</a>.

<li>New <b>Exit</b> buttons were provided for <i>Hide..</i> and <i>Center
Atom..</i>, replacing the former exit links.

<li>At the main page, enabled pressing Enter (in addition to clicking the
Submit button) to submit a PDB code to start a <i>FirstGlance</i> session.

<li>Fixed a bug that prevented the atom identification report
from displaying, to the lower left of the molecule, when the
first operation performed in the session was clicking on the
molecule.

<li>Fixed a bug in atom identification reporting that occurred
only in Mac Safari with the latest java update. This bug caused
the Safari window to disappear suddenly, at least after a recent
java update was released by Apple.

<li>Fixed several bugs that prevented the PDB identification code
from showing, to the upper left of the molecule, after the background
color changed.

<li> Minor improvements/corrections in documentation.

</ol>
<br><!----------------------------------------------------------------->
<li>May 3, 2006: Version 0.99 (with Jmol applet version 10.2.0).
<ol>

<li><b>Contacts..</b> is a new option to show atoms contacting
any "target" moiety, which is selected by clicking on the
molecule, or with the new <i>Find..</i> option (see next item).
Four views of atoms contacting the target are available, with
increasing levels of detail.
<a href="notes.htm#distances" target=_blank>
Distances can be measured</a> between
putatively non-covalently bonded atoms. Hydrogen atoms (if present
in the model) can be displayed.
<a href="notes.htm#contacts" target=_blank>
Seven kinds of non-covalent
bonds</a> can be displayed or hidden independently of each other.

<li><b>Find..</b> is a new option that puts yellow halos around atoms
designated by sequence number,
3-letter residue abbreviation, or element name. The halos are visible
in all views.

<li>A new <b><a href="snaps/index.htm">Snapshot Gallery</a></b> was
provided.

<li><i>More Views..</i> has a new option to show <b>all salt bridges
and cation-pi interactions</b> throughout the molecule.

<li><b>Isolated standard amino acids or nucleotides</b>, invisible
in the "backbone" displays of previous versions, are now spacefilled
in the initial view, and included in <i>Ligands+</i>
(<a href="notes.htm#lig" target=_blank>More..</a>). Selection of these was made
possible by a new Jmol command, "connected"
(<a href="bbinvis.htm" target=_blank>More..</a>).

<li>Solutions were implemented to handle hiding or selecting the
single <b>unnamed chain</b> in some PDB files, as well as ligands
that have chain designations (such as heme in 2HHD). These are important
in the new <i>Contacts..</i> target selection interface, and they improve
the function of <b><i>Hide..</i></b> over the previous release.

<li><b>Hide Hydrogen</b> was added to the <i>Hide..</i> interface.
This enables uncluttering ligands or non-standard
residues. (Example:
<a href="fg.htm?mol=1al4" target=_blank>1AL4</a> has hydrogen on both.)

<li>There is a new <i><b>Reset</b></i> link that attempts to reset
the session to the initial view, and most of the initial settings.
I've undoubtedly overlooked some things that need resetting.

<li><b>Gaps</b> in the coordinates, compared to the sequences crystallized,
can be located using new 

<script language='javascript'>
	document.writeln(makeNotesLink(
		"Sequences",
		"seq"));
</script>

documentation,
which links to the "SEQRES to Coordinates" alignment (S2C) resource by
Wang and Dunbrack.

<li>A <img src="gaps2.gif" align="center" border=1>
button for accessing the sequences and gaps help, and the link
to S2C (see previous item) was added to the main control panel, next to
the PQS, PDB, and OCA buttons.

<li>Most links and buttons now display <b>pop-up help</b> when the
mouse is held over them for a few seconds.

<li>The <a href="bugsjmol.htm" target=_blank>inability of Jmol to report
atom identifications when slab is on</a> has been handled better.
Slab is forced off when selection by clicking is needed (<i>Contacts..,
Hide..</i>). When Slab is on, the hover and echo identification reports
are replaced with a "Sorry..." message.

<li><b>Slab thickness</b> can now be controlled (3 steps).

<li>The definition of "<b>carbohydrate</b>" was greatly improved (for
the "hide carbohydrate" checkbox). See

<script language='javascript'>
// not essential here since we are not passing the PDB code from this doc.
	document.writeln(makeNotesLink(
		"Notes.",
		"predef"));
</script>

<li>Rare <a href="notes.htm#anomalous" target=_blank><b>Anomalous atoms</b></a>
are no longer invisible, but are shown as
<a href="notes.htm#anomalous" target=_blank><b>dots</b></a>.

<li>Hidden atoms are now listed by element, sequence number, and chain,
rather than by serial number. (Serial number is used internally.)

<li><a href="seqspecs.htm" target=_blank>
Specifications for a future interactive sequence listing</a> were developed.

<li>Updated many help documents, including

<script language='javascript'>
	document.writeln(makeNotesLink(
		"Notes",
		""));
</script>

and
<a href="issues.htm" target=_blank>Known Unresolved Issues</a>. Added a section
on selection of unnamed chains to
<a href="techinfo.htm#unnamed" target=_blank>Technical Information</a>.
A new list of <a href="bugsjmol.htm" target=_blank>Jmol Bugs and Limitations</a>
gathers together information scattered in other <i>FirstGlance</i> documents,
and buried in its javascript/Jmol script code.

<li>The help for <b>N->C Rainbow</b> now includes a spectral color sequence.

<li>Added a "mascot" image to the main page.

<li><b>mmCIF</b> format atomic coordinate files can now be loaded instead
of PDB format files, using a new Advanced Option available from the main
page. CIF files do not work properly in <i>FirstGlance</i>. CIF loading is
provided for testing purposes only. See
<a href="cif.htm" target=_blank>Preliminary CIF Observations</a>.

<li>Bug fixed: The axes, unit cell, and boundbox checkboxes under
<i>More Views..</i> did not work in Gecko browsers in FGiJ 0.98.

</ol>
<br><!----------------------------------------------------------------->
<li>March 13, 2006: Version 0.98 (with Jmol applet version 10.00.48).
<ol>
<li>Thanks to

<script language='javascript'>
	document.writeln(makeNotesLink(
		"Jaime Prilusky,",
		"uploads"));
</script>

<b>PDB files can now be uploaded</b> for display in <i>FirstGlance in Jmol</i>.
There is a new option on the main page to do this.

<script language='javascript'>
	document.writeln(makeNotesLink(
		"Instructions",
		"uploads"));
</script>

for
inserting such an upload slot into any web page are provided.

<li>Added a new view option <b>Hide..</b> that hides clicked chains,
residues/groups, or atoms; or all protein, DNA, RNA, or carbohydrate.
The hidden moieties remain hidden in all views, until explicitly re-displayed.

<li>Added a <b>PQS</b> "button" in the control panel (upper left panel,
near the PDB and OCA buttons).

<li><i>More Views..</i> now includes a new section on evaluating
<b>model quality</b>, with "color by temperature"
(thanks to Gale Rhodes)
and a link to MolProbity.

<li><i>More Views..</i> now includes checkboxes to show the
<b>axes, unit cell, </b>or<b> bound box</b>.

<li><i>More Views..</i> now includes a link for visualizing
<b>dipole moments</b> in Jmol.

<li>Added 1IGT (antibody) to the Gallery to provide an example with
disulfides in multiple chains, and both inter- and intra-chain disulfides.

<li>Fixed a bug in <i>Vines.., Hide Sidechains</i> that failed to hide
the sidechains in nucleic acids.

<li>Korea was added to the list of <a href="mirrors.htm" target=_blank>mirror
sites</a>.

<li>The advanced option to use browser frames was discontinued.
</ol>

<br><!----------------------------------------------------------------->
<li>February 2-12, 2006: Version 0.97 (with Jmol applet version 10.00.48).
<ol>
<li>The PDB code (or filename) is now the first word in the title of the
FirstGlance window. This makes it easy to distinguish windows showing
molecules from each other, and
from the FirstGlance main page window.

<li>
It is now possible to enter a <b>molecule's URL</b> into a form slot on the main page,
to display a molecule from any server
(in addition to a PDB identification code).

<li>
<b>Ligands+ are now shown by default</b> in the initial view. The definition
of <i>Ligands+</i> has been changed to exclude most non-standard
amino acids and nucleotides. When the <i>Ligands+</i> button is depressed,
or in <i>More Views..</i> (new, see below),
the accompanying help now includes a checkbox to <b>show non-standard
residues</b>.
The distinction between 
<i>Ligands+</i> and <i>Non-standard residues</i> is sometimes incorrect.
<a href="notes.htm#lig" target="noteswin">
Notes</a> were added to explain these definitions, and the examples of the
problems were documented.

<li><b>Disulfide bonds</b> are shown by default in the initial view,
in all backbone trace views, and in <i>Vines</i>.

<li>New entries in the <b>Gallery</b> illustrate disulfide bonds and
non-standard residues.

<li><b>Backbones are no longer interrupted</b>
by non-standard amino acids and nucleotides.
(Formerly, these were displayed as <i>Ligands+</i>, which
interrupted the backbones.) For more information, see the new
<a href="notes.htm#nsr" target="noteswin">
notes on non-standard residues</a>.

<li>In the <i>Vines..</i> display,
there are now (in the help panel) new checkboxes
to
<ol type="a">
<li><b>Hide sidechains</b>.
<li>Display <b>more detail</b>: all non-water atoms as sticks,
<li><b>Hide hydrogen</b>.
</ol>

<li>In the <i>Ligands+</i> display,
there is now (in the help panel) a new checkbox
to display <b>smaller ligands+ atoms</b>.

<li>When water is displayed,
there is now (in the help panel) a new checkbox
to display <b>smaller water atoms</b>.

<li>At the time of this release, mouse hover atom identification
reports were not working in OSX 10.3.9 (but worked in 10.4 and
Windows). Therefore, <b>clicking an atom now identifies it</b> at the lower
left of Jmol, and in the browser status line. The report to Jmol
required implementing pickCallback(), which may not work in some
browsers. A problem remains
reporting the element in these reports. The hover report remains, when
it works.

<li>Using clicking for atom identification required <b>changes in
the centering mechanism</b>. The former <i>Center All</i> link
was changed to <i>Center Atom</i>. The help accompanying the latter
offers a link to <i>Center All</i>.

	<ul><small>
<li>Turning centering off after
a single centering click was not possible, because in "set picking center"
mode, Jmol 10.00.46 does not call pickCallback(). Using "center atomno=" instead
of "set picking" could have avoided this, but it caused unwanted changes
in zoom.

<li>The present implementation was complicated by the need to turn
centering off automatically, when some view links or buttons are
pressed by the user before centering was turned off. This was implemented.

	</small></ul>


<li> The PDB code shown in Jmol at the upper left now changes
automatically to a contrasting color when the background is changed.
(Previously, it remained black, becoming invisible on a black background.)

<li><a href="issues.htm" target=_blank>Known unresolved issues</a> was revised,
and unimplemented plans for future enhancements were added.

<li>
Several <a href="mirrors.htm" target=_blank>
<b>mirror sites</b></a> are now listed.

<li>A new link <i><b>More Views..</b></i> has been added to
the upper left control panel. The links to additional viewing options
that were formerly in the introductory help have been moved to this
new help section, and expanded. New here is information about
<b>measuring distances and angles</b>, or opening the Jmol console for
<b>entering script commands</b>. In FirstGlance, default units for reporting distances
are &Aring;ngstroms (Jmol's default is nanometers, rarely used by protein
structure scientists).

<li>The link to <i>Protein Explorer</i>, formerly in the upper left
control panel, has been moved to the <i>More Views..</i> help section.

<li>The term <i>Structure Explorer</i> is no longer in use at
pdb.org. The link formerly of that name has been replaced with a PDB graphic.

<li>Adjacent to the PDB link, a graphic link to the
<a href="http://203.90.127.121/oca-bin/ocamain" target=_blank>OCA
Browser</a> Atlas entry has been added.

<li>
Fixed bug that reversed the <i>Charge</i> cationic/anionic colors in
the color key. (These colors were never reversed in the molecular view.)

<li>Fixed bug that reversed the <i>Solvent</i> and </i>Ligand</i> colors
in the <i>Composition</i> view. (Thanks to Frieda Reichsman for pointing
out this bug.)

<li>
Tested dozens of potentially problematic PDB files, documenting the
results. See links at the bottom of
<a href="about.htm" target="aboutwin">About FirstGlance</a>.

<li>Calcium ions are erroneously deemed "protein" by Jmol (through
10.00.48). Other metals appear to be correctly deemed "hetero" and "ligand"
(including at least Fe, K, Mg, Mn, Mo, Na, Zn, Cd). The command scripts of
FirstGlance were modified for the special case of calcium, to make it
display under "Ligands+". (Implemented Feb 4, 2006).


<li>Tried to prevent problematic atoms from remaining invisible (implemented
February 4, 2006).
<small><ul>
<li>Rarely, Jmol fails to deem standard amino acids as protein.
Therefore, "protein" was broadened to include the 20 standard amino acids
plus atoms deemed "protein" by Jmol, which (usefully) includes hetero
atoms for non-standard residues.
<a href="select.htm" target="selectwin">Examples</a>. Although the backbone
trace displays currently (Jmol 10.00.48) fail to connect the alpha carbons
of these amino acids, they are shown spacefilled to avoid leaving
these parts of chains invisible. An example is 1AL4.

<li>Rarely, Jmol fails to assign covalent bonds that should be present.
Such groups of atoms are invisible in wireframe (stick) rendering, the normal
rendering for the <i>Vines</i> display, which is supposed to show all non-water
atoms. Therefore, in <i>Vines</i>, all non-water atoms are shown spacefilled
as well as wireframe (or backbone). The diameter of the spacefill is the
same as the wireframe (or backbone); hence, when bonded, the spacefilled atoms are
hidden within sticks (or backbone). When not bonded, they are visible as small
spheres. Examples with many inappropriately non-bonded atoms are
1AL4 and 2SOC.

</ul></small>

<li>
Added additional information at the bottom of
<a href="techinfo.htm" target=_blank>Technical Information for Developers</a>.

<li>Added a free
<a href="http://www.sitemeter.com/stats.asp?site=s23firstglance" target=_blank>visit
counter</a>, kindly hosted by
<a href="http://sitemeter.com" target=_blank>sitemeter.com</a>. Clicking on the count
(below "Please be patient" when the application starts) reveals
referring sites, a world map showing locations of visitors, and browsers
and platforms used by visitors, among other useful information.
