Description
(Describe the actions that caused this problem to occur here)trying to open a session file that contained structure edited rotamers (to see possible mutations). the sesson file opened fine and then suddenly doesn't pen now.

This seems to be a model-hierarchy maintenance problem.

[Tom Goddard]

Can you provide the session file? If it is private then you can send a link to it directly to me (goddard@…), not to chimerax-bugs which is public.

Was the session made with an old version of ChimeraX? Which version? And was the "rename" command used to renumber models? Some older versions of ChimeraX renumbered models incorrectly and my guess is that invalid numbering is what was saved in this session. But those bugs were fixed long ago (1 year ago?).

[angrish.arvind@…]

Thanks for your response, Tom. I was using the latest chimeraX version and
I was generating rotamers for several residues (from structure editing),
but I didn't accept the rotamers as I wanted to compare the
original residues with possible mutant rotamers. There were more than 10
rotamer windows open in the session, and the session did open successfully
the first few times, but then finally gave the error which was reported. I
am not sure if I will be able to share the session file without permission
from my supervisor and other collaborators. I finally just accepted the
rotamers and superposed the WT structure to compare.

I greatly appreciate the chimera/chimeraX team for this wonderful software.

Thanks again.
Arvind.

Thanks for the info.  We'll try to reproduce the problem by saving sessions with unaccepted rotamers showing.  So let's not trouble to get your session as we can probably figure it out with the information you gave us.  It sounds like there is a problem with session saving of unaccepted rotamers so you might want to avoid saving sessions of those.  I'm on vacation until January 3, so will not investigate until then.

[pett]

This is pretty easy to reproduce:

open 1gcn
swapaa interactive /A:13 ILE

then save a session and restore it. That restored session has an extra empty rotamers-container group that is empty. If you then save and restore a session from that, you get the error reported in this ticket. I'll look into where the extra container group is coming from.

[pett]

The per-residue manager that tracks the active rotamers was creating an extra, spurious, container group model during session restore. The fix will be in tomorrow's daily build.
