[Freesurfer] Problem while fixing the Surface Topology

Hello FS Team, I had a question recently regarding an error encountered in the freesurfer recon-all. I believe error is the result of: mris_fix_topology -mgz -sphere qsphere.nofix -ga FirstOrderPoly lh CORRECTING DEFECT 3 (vertices=10731, convex hull=2557) normal vector of length zero at vertex 9

[Freesurfer] Normal vector of length zero

Hello Freesurfer Experts, I ran into the following error when running Freesurfer for one of our subjects, during: mris_fix_topology -mgz -sphere qsphere.nofix -ga FirstOrderPoly lh I could only find a partial answer to a previous post on a similar problem - pasted at the end. Following that, I l

[Freesurfer] Fixing Inaccuracies in White Matter Surfaces

Hello Everybody, This is Pradeep Reddy, just started my PhD in Medical Image Analysis and hence a newbie to FreeSurfer. I've passed the auto-recon2 stage in the reconstruction procedure. Now I am trying to verify WM segmentation produced by the recon-all/auto-recon2, before I move on to further p
