Hi Jixin

mris_divide_parcellation should do the trick. You can give it the max area of a parcellation and it will keep subdividing along the primary eigen-axis until no units are above that surface area.

Hellow,

Freesurfer could provide for every participant a standardized partition of the cortex into 66 regional areas. I do not know how to use freesurfer to subdivide these regional areas into a set of small and compact regions of about 1.5 cm2, resulting in high resolution atlas covering the entire cortex? Thank you!
