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

The ?h.area files are for the white surface and the ?h.area.pial for the pial cheers Bruce On Tue, 6 Oct 2015, chenhf_uestc wrote:
Dear Freesurfer experts, I have a question about the calculation of surface area. The cortical thickness is the distance between the pial and white matter. But, what ab

In addition, where can I find the definition of meancurv, gauscurv, foldi

curvind? I do not find it in the fswiki. Best, Feng
