Pymol Ray Tracing without wasting time

June 18, 2013

I often use the nice built in ‘ray’ raytracer in Pymol. These ray traces can take minutes to hours, and during that time I of course want to use my computer! Unfortunately, the Pymol window freezes during the ray trace, so when I switch virtual desktops it sometimes looks as if there’s a frozen terminal or similar there, which I click on, sometimes inadvertently, sometimes because I am a fool. This click gets queued up to Pymol and promptly delivered as the ray trace finishes – making the window redraw with the built in opengl, wasting all the time ray tracing, arg!

After doing this today during a 30 minute ray trace, I sat and thought for a few seconds and did the sensible thing:


PyMOL> ray; save ray.png

Chain the commands together so that it immediately saves the ray trace image, no matter what you do to the GUI in the meantime! I wish I’d taken the few moments to think this through back in 2009 or so.Image
