Calling matlab functions/ running matlab scripts from psychopy

[Jonathan O'Keeffe]

Hi,
    I am using the Basel Face Model to generate faces in matlab. I would like to generate faces according to the preferences of the subject during my psychopy experiment. I have written a script in matlab that will generate new faces and save them to disk.

So I am wondering what the best way to get a matlab script to run and then retrieve the newly generate files while in psychopy is.

Can anyone suggest anything?

Thanks, Jonathan

Hi Jonathan

if you can call your matlab script from a command line, you can do
this from psychopy:

from psychopy import core
cmd = "<your command-line matlab call here with arguments>"
out, err = core.shellCall(cmd, stderr=True) # returns stdout and stderr

simple pipes are fine on mac and *nix, not tested on windows. the
documentation is a bit sparse, http://www.psychopy.org/api/core.html,
so you might need to play around to see what works.
