Hi Abid, What troubles did you have with Spherical Demons? In any case, though using a different interpolation method, if the registration is the same, mris_preproc gives results very similar as the pycnophylactic method we described in the paper, as long as the data is smoothed. However, before s

Hi Freesurfer group, I wanted to use mris_preproc to calculate regional differences in surface area between two groups. Ideally I would like to use something that is vertex-wise and preserves regional area, but I've had trouble with spherical demons (using the Winkler methodology). So I am going
