Dear list, Is there a paper or any documentation describing how freesurfer tessellate and smooth cortical surfaces? In particular, does freesurfer use any specific variety of marching cube isosurface algorithm? Regular surface smoothing (like the Laplacian smoothing) may cause undesired surface shrinking. It looks that freesurfer does a good job on surface smothing. So I'm wondering what smoothing algorithm freesurfer employ.
Thanks, Kai
