You're command line is incomplete (it needs more than just --s). Run it with --help and/or visit the wiki page

Thank you so much for the response! Unfortunately, that is the full command line and output:

Hello FreeSurfer Developers,

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 (MailScanner has detected a possible fraud attempt from "secure-web.cisco.com" claiming to be 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):

  Illegal instruction: 4

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

1) FreeSurfer version: freesurfer-darwin-macOS-7.2.0-20210713-aa8f76b
2) Platform: macOS Monterey, version 12.2.1

Thank you!
Alice
