Dear Freesurfer,
I have checked the mail list, none could answer my problem. I added up the value of all vertxes in the .area or .area.pial files, find that brain size did not contribute much to that vertex-sum. However, some experiment used total brain volume as a regreesion coefficient to remove brain size effect. In these case, with the comparison of surface area in vertex-to-vertex, is it proper to use the above vertex-sum as the regression coefficient to remove different brain size? Thank you very much!
