Hi Arsenije

in general please send us text output, not screen shots.

The tilted head shouldn't be an issue, but the XL defect is. You should check to make sure that nothing went badly wrong (e.g. skull stripping, talairach) as we usually don't get defects that are that big unless the data is pretty low quality

Dear Freesurfer experts,

I was processing one of my subjects, but ran into a problem as a XL Defect was detected. The following output was seen (attached screenshot). From examining all of my volumes it seems that they are tilted a bit, but I'm not sure if that is the reason.

Thank you for your help.

Best,

Arsenije
