[Mne_analysis] Vertex mapping for fsaverage

[sheraz at nmr.mgh.harvard.edu]

Hi Tim,

There is vertices field inside stc structure if you open it in Matlab.
Just add 1 to it, it will correspond to vertices on fsaverage brain.


stc = mne_read_stc_file(stcfile);
fsAverageVertices=1+squeeze(stc.vertices(:,1));



Regards

Sheraz
