Hi, I would like to use Chimera ConSurf scripts in ChimeraX, but I get the following error when I try to run the script on ChimeraX ModuleNotFoundError: No module named 'cPickle' File "consurf_final_zn.py", line 1, in See log for complete Python traceback. If you wish to report this error, send mail to chimerax-bugs@cgl.ucsf.edu <mailto:chimerax-bugs@cgl.ucsf.edu> and describe what you were doing and include a copy of the contents of the log. Don't include any data you wish to remain private since a publicly viewable bug report will be created. Is this something that can be fixed or updated? More generally I would like to update ConSurf with a version of the script for ChimeraX, can you help me with that? Here is the beginning of the original chimera script import cPickle, base64 try: from SimpleSession.versions.v65 import beginRestore,\ registerAfterModelsCB, reportRestoreError, checkVersion except ImportError: from chimera import UserError raise UserError('Cannot open session that was saved in a' ' newer version of Chimera; update your version') checkVersion([1, 12, 41623]) import chimera from chimera import replyobj replyobj.status('Restoring session...', \ blankAfter=0) replyobj.status('Beginning session restore...', \ blankAfter=0, secondary=True) beginRestore() def restoreCoreModels(): from SimpleSession.versions.v65 import init, restoreViewer, \ restoreMolecules, restoreColors, restoreSurfaces, \ restoreVRML, restorePseudoBondGroups, restoreModelAssociations molInfo = Thanks a lot, Best, Fabian Fabian Glaser PhD Head of the Structural Bioinformatics section Bioinformatics Knowledge Unit - BKU The Lorry I.
