Hi Jeff there are two utilities we provide for this (and yes, David is always correct!):
1. mris_make_face_parcellation - create approximately unifom-sized parcels using icosahedral subdivisions. These can be uniform in the native space using the ?h.sphere, or in register and uniform in the group space using ?h.sphere.reg. 2. mris_divide_parcellation - divides an existing annotation file (e.g. lh.aparc.annot) either with a specific set of divisions specified by the user, or so that no individual parcel is greater than a specified surface area. cheers Bruce On Tue, 18 Jun 2013, Jeff Eriksen wrote: > I just attended the pre-OHBM FSL/FS course, and spoke to David Salat there > about possibilities to create more detailed sub-parcellationsfrom the two > major structural atlases.
