[Freesurfer] Segmentation of the Hypothalamus in FreeSurfer 7.4.1

External Email - Use Caution

Dear FreeSurfer Expert,

I am trying to segment the subunits of the hypothalamus using FreeSurfer 7.4.1, but the segment_subregions command does not include an option for the hypothalamus in this version. I found that version 7.2.0 includes the command mri_segment_hypothalamic_subunits, but this command is not executable in version 7.4.1.

My questions are:

1. Do I have to downgrade to 7.2.0 to use this function? 2. Why was this function discontinued in version 7.4? Was it removed due to defects or other issues? 3. Is there any alternative way to segment the hypothalamus in FreeSurfer 7.4.1?

Best,

Juen
