Hi Antonio
it's tough to diagnose from one slice. Is the top of the head in general darker than the bottom? It looks like it, but that might also be lower myelin content. If you upload the subject we'll take a look.

Dear Freesurfer experts,
I am trying to run cortical thickness analysis on 4-6 yrs old patients but I have some problem to get nice cortical gray matter. I have tried to run several N3 but with no success so I would need to ask whether you could give me hints to improve that. Please find attached a screenshot of what I do get.
Many thanks for any help.
Best Wishes
Antonio
