I'm attempting to use the mri_segment_hypothalamic_subunits tool on subjects that have been analyzed with recon-all as described on the wiki page (https://surfer.nmr.mgh.harvard.edu/fswiki/HypothalamicSubunits), but I received the following error when I run the mri_segment_hypothalamic_subunits command (mri_segment_hypothalamic_subunits--s):

Does anyone have any suggestions on how to trouble-shoot this problem? recon-all does not seem to have any issues.
