Hi Bruce Thank you for the quick answer. We already considered using mris_divide_parcellation. Unfortunately the result is a strip shaped parcellation scheme, which is not suitable for our aim. Therefore we would rather use mris_make_face_parcellation. Is there no other way to get the MNI Coordinates of these vertices and the label corresponding to them?
Thanks very much for your help!
