@*~RSC_HELP_SEQUENCE_GROUPS
A sequence group (SG) is a user defined set of sequences.
Strap provides two operations on SG:
- Showing/Hiding all sequences in a group.
- Selecting/Unselecting all sequences in a group.
To define a group of sequences, the respective sequences need to be selected.
In the introduction tutorial, different methods to select sequences are discussed.
Selected sequences are indicated by a blue background in the alignment row header.
Once the sequences are selected, the user can define a sequence group by one of the following two methods.
1st Method: Sequence lists
Right clicking one of selected sequence names brings up the context menu.
The first menu item opens a list representation of those sequences.
Below this list are buttons that act on the list: Select/unselect and view/hide sequences.
2nd Method: Shortcut keys
Select some sequences. Focus the alignment pane by left-click.
Typing capital letter G followed by a letter or digit defines a group of sequences.
Each group is identified by a letter or digit.
Sequences in a group can be acted upon:
- g Group-ID: Shows only the sequences of that group
- h Group-ID: Hides the sequences
- d Group-ID: Displays and selects the sequences. Previously selected sequences are deselected.
- D Group-ID: Displays and selects the sequences.
- U Group-ID: Unselects the sequences
Sequences that are not shown are listed in the object tree at the left panel.
To see the tree, drag the right divider to the right.
Use Drag-And-Drop or the context menu to render hidden sequences visible.
