Re: [Freesurfer] Vertex wise surface area values?
I was not able to replicate with subjects that I have. Does the same thing happen if you use the subject as the target instead of using fsaverage? If so, then upload the subject for me so I can replicate doug On 4/11/14 7:30 AM, Sabin Khadka wrote: Hi all, I am trying to extract vertexwise surface area values in an ascii files.
