Hi Tom, hi Eric, thanks a lot for Eric's suggestion! This is very neat and works like a charm! @Tom: In a "normal" python script importing code from another module in the same directory is actually not a problem. As far as I understand, that is because calling "python http://myScript.py" prepends myScript's directory to sys.path (see e.g. https://docs.python.org/3/library/sys.html#sys.path With pymol this also works, which is how I got used to organising all my pymol scripts that way. I suppose opening a script with chimerax just doesn't prepend its directory to sys.path then and there is no simple way to change this? Thanks a lot once more, Maik ________________________________ From: Eric Pettersen <pett@cgl.ucsf.edu> Sent: Thursday, April 18, 2024 3:13:10 AM To: Engeholm, Maik Cc: chimerax-users@cgl.ucsf.edu Subject: Re: [chimerax-users] import from local file in chimerax-python script Hi Maik. I don't know if this is the "correct" solution, but this code in http://myScript.py will put those class definitions (well, any global definitions in http://classDefinitions.py into http://myScript.py's global namespace: from os.path import join, dirname with open(join(dirname(__file__), "classDefinitions.py")) as f: exec(f.read(), globals(), locals()) --Eric Eric Pettersen UCSF Computer Graphics Lab On Apr 17, 2024, at 2:03 PM, Engeholm, Maik via ChimeraX-users <chimerax-users@cgl.ucsf.edu<mailto:chimerax-users@cgl.ucsf.edu>> wrote: Hi there, I'm running a python script either from within ChimeraX (with "open http://myScript.py") or from the command line (using "chimerax http://myScript.py"). As the script gets longer and longer, I would like to store some class definitions in a separate file (http://classDefinitions.py within the same directory as http://myScript.py and then import those into the main script with some command like "from classDefinitions import testClass". This, however, gives me an "ModuleNotFoundError: No module named 'testClass'". What is the correct way to do this? Any help would be much appreciated!
