As per Elaine's mail, great cover!  As for the session issue, since the last production release I've completely redone session handling.  There are no longer PDB files embedded in sessions.  Instead, structures are built directly by the session.  Also, attributes that are the same for all atoms (or residues/molecules) are recorded once instead of once per atom.  As a result, sessions are smaller, use less memory when restoring, and restore faster.  This new session code is in the 1.2224 snapshot release.  If you try out 1.2224 and you still can't get a newly-saved session to restore (i.e. a session that was written using 1.2224), then let me know and I'll investigate to see if there are further bottlenecks I can eliminate.

Notepad++ will do a great job of editing the .py files.  I've found

the files.

On a related issue, I have a question regarding the saved sessions.
In some of the viral capsid models I've created a saved session is
enormous (about 60 megabytes) and fails to compile either
automatically when loading the .py session or manually using the
python.exe included with Chimera.  It seems to be a result of
excessive explicit attribute assignments that I don't really care
about (color etc) since they are easy enough to set once the model has
loaded.

Does anyone have any suggestions or experience with this issue?

PS: Check out the most recent issue of Science.  Although the editors
chose the least visually impressive submission, non of the variations
would have been possible without Chimera: great program.

Hello. My name is Anne Szklarski and I am a student at The College of New
Jersey. I was wondering if there was a way that the python files could be
modified in notepad. Does it require the Python software? The reason I ask
is because I have been renaming certain atoms in the .ent files using
notepad so that I may specifically select them in chimera. The only
problem with my current method is that I have to start the rendering
process from the beginning which is quite time consuming. So I was
wondering if there was a way that I could alter the chimera file directly
and not lose any of the colors, etc. that I have chosen. I appreciate any
information on this matter.

Thank you,
Anne Szklarski
