Hi freesurfers,
I am doing a connectivity analysis on cortical areas. I load the 2d fmri surface file in fsaverage5 space into matlab and I get 20484 vertices for both hemispheres. Some of which are zero because I previously specified to get only the cortex vertices. However, the number of non-cortex vertices changes across subjects.
Is it possible to get from fsaverage5 any overlay mask that specifies if it is cortical or not, so when I load it into matlab i can get a logical vector of 20484 elements?
Thanks Dorothy
