Dear Freesurfers, When I run the freesurfer 6.0 recon-all -hippocampal-subfields-T1 command to segment a MNI152 template, the resulting segmentation of the left hippocampus is flipped in right-left dimension. Otherwise the right hippocampus and the subcortical segmentations in the aseg-file look fine. I encountered a similar problem when I segmented a 7T scan. Would you know what might cause this how to fix it? Thanks so much for your advice!
