Thanks Bruce! Unfortunately when I try to open the lh.defect_labels it quits freeview. The lh.orig.nofix loads okay, but I was wondering if it was a problem that this file is even called "nofix", does that mean it was not able to correct for defects?

Hi Chemda
Usually that means something big has gone wrong in the segmentation or skull stripping (like the cerebellum is still attached to a cortical hemisphere in the wm.mgz or the skull is or something like that). More generally this happens when there is a topological defect that is too big to automatically correct in a reasonable amount of time. You can visualize the defects following the instructions here:

External Email - Use Caution *Hi,
My name is Chemda Wiener. I am a PhD student in a Neuro-Engineering lab. We are working with MRI scans of patients with epilepsy and I am attempting to use freesurfer to create the mesh .pial files. When I run the freesurfer recon-all command, the command gets stuck at "correcting defects" with the last file it creates being the "lh.defect_chull". It has been stuck for a few days on this part until I finally killed the process. I tried running autorecon2 afterwards on this patient to see if it can pick up from where it stopped but it gets stuck again at the same place.
I would appreciate any help in the matter.
Thank you in advance for your time and your software!
