Hi Bruce and Doug, Thanks so much for the advice. I think I'll try to hack something together since I have to perform this step for numerous subjects. One quick question - is the order of the vertices preserved between the pial curv and spherical curv ascii files? Thanks again, John On 11/9/1

there used to be something built into tksurfer to do soap bubble smoothing. You can try smooth_vals_spare from the tcl prompt. I think it depends on setting the fixedval field in the vertex struct to 1 for the stationary points of the soap bubble. You can first read in a file that is 1 for the

Sounds like you are trying to do soap bubble interpolation (?). I don't think we have a binary for that. Maybe Bruce knows of one. You could hack something together, with smoothing (mri_surf2surf), creating binary masks (mris_binarize), and masking (mri_mask), and basic math operations (fscalc

Hello all, I'm in the process of mapping some non-FreeSurfer derived outcomes to a curv file containing the vertices of the pial surface mesh. I have values at roughly 100 vertices, leaving some 37000 with 'nan'. I then run an intra-subject surf2surf command in an attempt to interpolate betwee
