I have used the following command: mri_segment_hypothalamic_subunits --i /home/user1/data/scans/ --o /home/user1/data/segmentations/ --vol /home/user1/data/hypothalamic_volumes.csv I am using FreeSurfer version 8.0.0. Am I forgetting any important flag in the command? Any help to solve this issue would be appreciated. Thank you very much for your time. Best, -- Miguel Ángel Rivas Fernández
