[Freesurfer] HC Subfields LongHippo

Dear Freesurfer Community,

I ran the Freesurfer longitudinal pipeline for my subjects (7T, T1_data, 2 timepoints each). Now I want to continue with the longitudinal segmentation of hippocampal subfields: https://surfer.nmr.mgh.harvard.edu/fswiki/LongitudinalHippocampalSubfields

However, when I want to run the command: longHippoSubfieldsT1.sh <baseID>

I get the error message "bash: longHippoSubfieldsT1.sh: command not found"

First thing I did, was checking the Freesurfer folder for the longHippo..sh file. I am using FS 6.0 but the file is not available.

So my questions: where can I get the file longHippoSubfieldsT1.sh or what else can I do to proceed with the HC subfield segmentation?

Thanks a lot for your support Best Sebastian
