External Email - Use Caution Hello FreeSurfer Team, I am trying to compute the local Gyrification index on my subjects with recon-all -s -localGI. Running this under FS 6.0 runs without errors, with FS 5.3. I get: mesh_outer = struct with fields: vertices: [68598x

External Email - Use Caution Hi, I am trying to understand how exactly FreeSurfer estimates the curvature values from the white surface. From the mailing lists I understood that the white surface is modeled by fitting a second-order polynomial function and curvatures are estima
