The value at each vertex of ?h.white.avg.area.mgh is the average area at that vertex averaged over all the input subjects. Note that the area of a vertex in the average subject will likely be much less and is not particularly meaningful. I'm not sure if this answers your question or not..

Dear FS team,
I'm writing matlab code to obtain smaller parcellated regions of equal size starting from the freesurfer parcellation performed on the average subject. Should I apply a scale factor If I wanted to use the areas stored in ?h.white.avg.area.mgh for the new parcellation? My Freesurfer release is 4.2
Thanks in advance for your help.
Best, Rafa _______________________________________________ Freesurfer mailing list Freesurfer@nmr.mgh.harvard.edu https://mail.nmr.mgh.harvard.edu/mailman/listinfo/freesurfer
