Hi Grant, The editing facilities in Multalign Viewer are somewhat basic and could stand improvement (e.g. undo would be nice). You can only move a region in a certain direction if there is a gap somewhere ahead of the region that can be removed and placed behind the moving region. MAV won't increase the length of your alignment (by placing an all-gap column on the end) in order to allow the motion [this is mentioned in the docs]. A workaround is to save your alignment to a file and edit the file to add the all-gap columns necessary to allow your motion. I would suggest FASTA or PIR formats, since those are the simplest to change. Of course, at that point you may be able to make all the changes you want with a text editor and just cut MAV out of the loop -- it would depend on what you're doing. --Eric Eric Pettersen UCSF Computer Graphics Lab pett@cgl.ucsf.edu http://www.cgl.ucsf.edu On Oct 27, 2005, at 4:09 AM, Grant Jacobs wrote:
While the help notes for the alignment editor says that gaps can be created, I can't see how! Surely I'm missing something...
Selecting a residue or set of residues to create a region, then applying ctrl-left-arrow (or right arrow) yields an error complaining of a lack of gaps in the region ("No gap available in <seq name>"). This makes me think that regions can only be moved if they are already bounded by gaps. Which in turn leaves me stumped as how to create the initial gaps manually...!
What I had expected was for it to insert new gaps to the let of the region if applying ctrl-right-arrow to a region and vice versa for using ctrl-left-arrow.
