hi bruce,
I'm not positive I understand what you want. Have you tried
mris_divide_parcellation?
how do i use mris_divide_parcellation? any documentation somewhere?
the basic idea is to create some form of voronoi tesselation of a region constrained by a parameter n_sub_regions.
subj1: aparc.annot -> e.g i want to break up stg into 6 regions subj2: break up stg also into 6 regions such that there is a one to one correspondence between the subj2 regions and subj1 regions.
cheers,
satra

hi john,
thanks. that's the idea, but what i want is that sub-division is done within regions that are either determined automatically through the freesurfer classifier or through manual parcellations. not a fixed template of parcels that's transferred via the spherical registration.
cheers,
satra

Would the Lausanne2008 template from the connectome mapping toolkit not do the trick?
