Thanks Tom, How do you invoke this python shell? A quick google search turns up nothing. The command line in the chimerax app does not allow tab completion. I've tried running 'chimerax --nogui' from the command line and that gives me a shell but no tab completion is possible there either. ________________________________ From: Thomas Mulvaney <thomas.mulvaney@cssb-hamburg.de> Sent: Wednesday, April 19, 2023 1:36 PM To: BARRY E DEZONIA <barry.dezonia@wisc.edu> Cc: chimerax-users@cgl.ucsf.edu <chimerax-users@cgl.ucsf.edu> Subject: Re: [chimerax-users] Hopefully simple plugin development question Hi Barry, The list of current models the user is viewing is in the `session.models` variable. Assuming the user has only one PDB file open, you can just do `session.models[0].filename` which will return the path to the PDB file they opened. I've discovered most of the functionality I needed by poking around in the Python Shell that ships with ChimeraX and hitting tab to find out the attributes and methods that objects have.

I know how to do this. What I want to know is how to find the current model's name / associated pdb filename from my plugin. Imagine my plugin really is just a "Run" button that looks up the current model, generates the associated pdb filename, and passes that name to my python script. Can someone tell me how in a chimerax plugin I can make the call that will give me the pdb filename I want? I've read much of the developer docs and could not find what I was looking for. _______________________________________________ ChimeraX-users mailing list ChimeraX-users@cgl.ucsf.edu<mailto:ChimeraX-users@cgl.ucsf.edu> Manage subscription: https://www.rbvi.ucsf.edu/mailman/listinfo/chimerax-users
