Hello Victor,

If you used the 7.1.1 installer package, https://surfer.nmr.mgh.harvard.edu/pub/dist/freesurfer/7.1.1/freesurfer-darwin-macOS-7.1.1.pkg, then it should have installed /Applications/freesurfer/7.1.1 for you.  I believe the same is true for the 7.1.0 installer, i.e., /Applications/freesurfer/7.1.0, and similarly for the 7.0.0 installer.  We set it up that way so the distributions would be separate.  This allows people to switch among/compare the distributions by setting FRESURFER_HOME differently, e.g., 

$ export FREESURFER_HOME=/Applications/freesurfer/7.1.1
or
$ export FREESURFER_HOME=/Applications/freesurfer/7.1.0
etc…
.. then source’ing the shell setup script for either sh or csh, e.g., for sh
$ source $FREESURFER_HOME/SetUpFreeSurfer.sh

The installer packages create an uninstall script under each distribution, e.g.,  /Applications/freesurfer/{7.1.1, 7.1.0, 7.0.0}/uninstall.sh.  So if you wanted to start with a clean install you could try running the uninstaller script(s), and then re-install using the .pkg files, e.g.,  to run the 7..1.1 installer,

$ sudo /Applications/freesurfer/7.1.1/uninstall.sh

Hi Victor,
I highly recommend that you keep both installations separate.

Subject: [Freesurfer] question about mri_segment_hypothalamic_subunits
 
​Hi all, 
 
I installed the most recent dev version of FS7.1, and copied its files over the old FS7.1. I entered sudo mri_segment_hypothalamic_subunits into xquartz, and receive an error: 
 
error: freesurfer has not properly been sourced
 
I am using mac os Catalina 10.15.6. How can I fix this?
