Dear Mr or Ms Is there any way that we can obtain curvature value of the pial surface? I am not sure whether lh.curv is the curvature file that I want. How can I calculate the mean curvature, Gauss curvature of the pial surface and the GM/WM interface? Is there any built-in function in freesurfer to calculate the above index? Is there any other measures of cortical foldings in freesurfer besides lGI and curvature? Thanks a lot! yczhang
