In my dataset I have 4 subjects where the T1 was acquired, planning the FOV very close to the occipital lobe. I guess that triggers the error: getSignalBehindHead ERROR (no slices behind head) WARNING: only 0 < 7 slices behind head! ERROR: xcerebralseg  and results in gtmseg exited with errors.

How can I fix this?

Best regards,

Boris
