Rafa,
Not sure if this will help, but Bruce recently created a utility to generate a parcellation based on which icosahedral face each vertex maps to. Its called mris_make_face_parcellation, and you can get it here:
ftp://surfer.nmr.mgh.harvard.edu/pub/dist/freesurfer/misc/
ex.: cd <subj>/surf mris_make_face_parcellation \ lh.inflated \ $FREESURFER_HOME/lib/bem/ic3.tri \ lh.ic3.annot
then:
tksurfer <subj> lh inflated -annotation ic3
there are other 'ic' files in that bem dir to try, to give you different number of faces.

Dear FS team,
I'm writing matlab code to obtain smaller parcellated regions of equal size starting from the freesurfer parcellation performed on the average subject. Should I apply a scale factor If I wanted to use the areas stored in ?h.white.avg.area.mgh for the new parcellation? My Freesurfer release is 4.2
Thanks in advance for your help.
Best, Rafa _______________________________________________ Freesurfer mailing list Freesurfer@nmr.mgh.harvard.edu https://mail.nmr.mgh.harvard.edu/mailman/listinfo/freesurfer
