[Freesurfer] XL Defect Correction

Dear Freesurfer experts,

During my recon-all I encountered a problem for one of my subjects, where the process got stalled at "CORRECTING DEFECT 12 (vertices=21293, convex hull=1791) XL defect detected...".

I've checked the output and it seems that skull-stripping hasn't been performed properly, but I do not know exactly if there are any other underlying issues. I've attached some screenshots for your consideration. I know that some defects can be fixed using manual correction or using control points, but I'm unsure exactly of what steps to take going forward.

I appreciate your help and any input.

Best regards,

Arsenije
