Align
The Dialog is used to align a
number of selected proteins (see ent).
The user selects an alignment method 
.
By pressing the button 
the alignment
computation is started. It takes some seconds to minutes, before the
computation the result is shown in a preview panel.
To accept the alignment in the preview and to infer the alignment into
the working alignment panel
needs to be pressed to.
3D-alignment programs consider the 3D-structure.
If not all proteins have 3D-coordinates, then the Strap uses a combination of
3D- and sequence alignment.
