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.

Hope that helps,

Tom

Hello,

I am looking at writing a plugin for chimerax that takes a pdb and runs some python code that will calc some stuff hand stuff to other programs. 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.
