Hi Doug - yes they do actually, I was quite pleased. I did some trials with other subjects and the mri_vol2surf all looks good. Very similar to what I had in our in-house software.
Would things be better if I were to isolate each sulcus as a .label and then try the mri_label2label? Someone suggested perhaps the colours are overlapping with the overlay.... -- Ph.D. Candidate McGill University Integrated Program in Neuroscience Psychology On Wed, Jun 15, 2016 at 4:10 PM, Douglas N Greve <gr...@nmr.mgh.harvard.edu> wrote: > The problem is probably that the vol2surf command did not properly > sample the labels onto the surface.
