Hi Justin, This is quite similar to a question I had asked previously: https://www.mail-archive.com/freesurfer%40nmr.mgh.harvard.edu/msg33421.html I believe the solution is to generate a 14000 vertex template, and then appy mri_surf2surf to all 10 subjects, which will map the vertices of all 10 subjects to your template. The 10 transformed surfaces should then correspond with one another.

Dear FreeSurfer,

I am a beginner in FreeSurfer and wonder if it is possible in FreeSurfer to apply the same triangulation across multiple subjects, i.e. the same number of vertices and triangles at the anatomically identical locations. For instance, I have 10 subjects and want to have pial (or white matter) surfaces of individual subjects consisting of 14000 vertices which are anatomically matched. Any suggestion will be greatly appreciated.

Justin.
