Hi,

Is there a way to know, when working in matlab, which sources a  
freesurfer label includes? I'm working with stc files morphed onto  
fsaverage. Each of them has 10242 sources, whereas fsaverage labels  
refer to 163842 vertices. Is it possible to figure out the mapping  
between freesurfer and mne surfaces?

Thanks,  
Yigal

Hi,

Attached is a little function which picks the correct time courses  
from an stc file given a label file and an stc file. This will be  
included in the next version of MNE.
