Thanks, Bruce So, in the stats folder of each subject, the
lh.aparc.a2009s.stats file provides surfarea of each region. This value

Is the area of each vertex obtained by the average the area of triangles su
rrounding the vertex? Best, Feng

Hi Feng
we compute the surface area of each surface and store it separately. The
?h.area files are for the white surface and the ?h.area.pial for the pial
