0.9 should be able to open all 0.8 sessions.     -- Greg On 7/2/2019 8:57 AM, Yehuda Halfon wrote:

Ok thanks,

I'll install the new 0.9 in parallel to the 0.8 so we can open the old sessions.

There was a bug when saving that session, so that session file is unusable. We have changed ChimeraX, so if there is a problem saving the session, it will let you report that as a bug instead of leaving you with an invalid session file.  The fix is in ChimeraX 0.9.  However, at this stage of ChimeraX's development, we recommend that you often.  At least as often as when there are production releases :-).  Monthly, wouldn't hurt.

Hi all,

I'm using chimeraX 0.8 (2018-12-17) on centos 7 (can't remember the build).

Sometimes when I load a session that was saved using this version of chimeraX it gives me this error:

Unable to restore session, resetting.

Traceback (most recent call last):

File "/software/graphics/chimerax/lib/python3.6/site-packages/chimerax/core/

session.py", line 593, in restore

obj = sm.restore_snapshot(self, data)

File "/software/graphics/chimerax/lib/python3.6/site-packages/chimerax/

std_commands/view.py", line 214, in restore_snapshot

for k,v in data ['view attrs'].items():

TypeError: 'NoneType' object is not subscriptable

After that I can't open the session again, so I need to remake it.

Help,

Yehuda Halfon
