[chimerax-users] Hopefully simple plugin development question

[BARRY E DEZONIA]

Thanks Tony. That command line interface is what I have been using (for instance to run the devel tools). It does not have tab completion. I am wondering what command line Tom is using that does have tab completion.

That tip model.opened_data_format.name<http://model.opened_data_format.name> will come in handy. I just really need to find the "current" model/view window and then use the session variable or else metadata available to the model/view to get it's model id or model name that I can then match to the session.models[] variables.

Barry,

The shell tool is under Tools -> General on the ChimeraX menu. There's some API documentation online here: https://www.cgl.ucsf.edu/chimerax/docs/devel/index.html.

Models should also have an 'opened_data_format' attribute with info about which file parser was used (e.g. model.opened_data_format.name<http://model.opened_data_format.name>). This could be one way to limit models to only PDB or whatever you'd be able to support.

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.

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.
