Dear all, I'm preparing a movie in chimeraX on macOS. There are more than 25 maps opened and also another 20 low-pass filtered maps generated within chimeraX by "vol gaussian". There are also ~20 pdb models, several positions saved by "view name" and ~20 2dlabels. I got the following error message when I save the .cxs file, and the session was not saved. RuntimeError: Unable to restore objects of LabelModel class in ChimeraX-Label bundle because the class name is not listed in the name to class table for session restore File "/Applications/ChimeraX_Daily.app/Contents/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages/chimerax/core/session.py", line 142, in from_obj (obj_cls.__name__, bundle_info.name)) See log for complete Python traceback. The session is still alive, and I have no problem when I save other much simpler sessions. Is there a way that I can get this big session saved? Is the error related to 2dlabels? Many thanks, Yixiao
