Hi Valeria

what version are you running? It's hard to tell from a single slice, but what is the white-matter appearing stuff that is outside the white matter surface? I think that is what's messing stuff up. If you want to upload the data subject one of us will take a look (that is, upload the entire subject directory)

cheers Bruce

Dear Freesurfers,

I usually get very satisfying results but in my last analysis I noticed some errors in a few subjects' pial surface (see attached example image). I really don't get how it failed in that way. What I know I can surely do is to manually modify the WM and run again the autorecon command.

Could someone kindly advice me on how to avoid/solve the problem in a less time-consuming way? Thank you.
