Hi Gonzalo, Download the .tar.gz files for the versions you're interested in and extract to different directories. https://surfer.nmr.mgh.harvard.edu/pub/dist/freesurfer/
Then to run a particular version, set the environment variable FREESURFER_HOME to the install directory of version you would like to use, then run source $FREESURFER_HOME/SetUpFreeSurfer.sh if using a bash terminal, or source $FREESURFER_HOME/SetUpFreeSurfer.csh if using a C shell terminal. -Paul ________________________________________ From: freesurfer-boun...@nmr.mgh.harvard.edu <freesurfer-boun...@nmr.mgh.harvard.edu> on behalf of Gonzalo Rojas Costa <gonzalo.rojas.co...@gmail.com> Sent: Friday, February 3, 2023 5:26 PM To: freesurfer@nmr.mgh.harvard.edu Subject: [Freesurfer] installation of two versions of freesurfer on same computer...
