Dear FS experts
I tried to preprocess two T1-w. scans from a 7T scanner (dimensions 448x448x180; resolution 0.5x0.5x0.8mm) but the Talairch quality check failed.

Do you have any idea why that problem occurred? Does anyone have experience with scans acquired at 7T and FS? Another question is whether we can run FS with a resolution smaller that 1x1x1mm (larger matrix that 288x288x288)?
Thanks in advance Best regards Juergen Haenggi
