I am experiencing a problem with 4 participants. Whrn I open the brainmask with freeview, it appears white (binarized). I was editing this brainmask and at sone point I switched something and it changed to white. I deleted alk the files and I run recon-all - autorecon1. The problems persists and recob-all -autorecon1 finished with errors. I do not know how to solve this problem. I would much appreciate your help.

Best regards,

Rosalia
