By default, pymol seems to grab the number of cores on the system for rendering. How can I force it to only use one core?


I have a large collection time-series of of coordinate data from a computational protein folding experiment. I'd like batch render the generated pdb files into a movie in a programmatic way. Pymol however likes to eat up as many cores as it finds available. I'd like to retain some control of the computational burden (required for some computational cluster jobs). How can I force pymol to only use one (or n) core(s)?


While the question was closed (as it was decided to not fit into biological criteria of the site) future visitors might find it useful to know the answer:

set max_threads, 1

The solution was found in a Biostars question.

    $\begingroup$ I'm all for bioinformatics questions, but this one has absolutely no biological component to it. $\endgroup$ – Daniel Standage May 3 '12 at 18:03

    $\begingroup$ @DanielStandage I only posted this question since I saw a high voted question here on pymol scripting: biology.stackexchange.com/q/732/822 Again let me know if this is not the intention of the site. $\endgroup$ – Hooked May 3 '12 at 18:07

    $\begingroup$ I think bioinformatics questions can definitely be on-topic for this site, assuming they include a significant biological component (or at least some biological component). The question you refer to includes as least a minimal description of a biological question being addressed, whereas this one focuses entirely on the software aspect. $\endgroup$ – Daniel Standage May 3 '12 at 18:46

    $\begingroup$ @NickT It would depend on what the scope of the Builders.SE site was, as per their FAQ. Our FAQ states: "Questions on interdisciplinary subjects like bioinformatics are also welcome, as long as they focus on the biological part of the subject." $\endgroup$ – Daniel Standage Jun 22 '12 at 10:25
