[Freesurfer] Extracting values from a single vertex

External Email - Use Caution

Hi FreeSurfer users,

I want to extract thickness values at a single vertex. I searched on the support list and found an mris_convert command to use. However, the file I want to extract values from is a volume with multiple frames. When I try to use mris_convert on it, I only got the value at a vertex on the first frame. The goal is to set that vertex as a seed point and use the values as a regressor for glm. Is there a way to do this with FreeSurfer's commandline tools, or should I do this in Matlab?

Mahalo,
