Can anyone advice me on how to set the environment variable FREESURFER_HOME for installing it in OS X 10.6.8 (with XQuartz installed)? My directory for Freesurfer: /Applications/freesurfer I know I also have to add: setenv FREESURFER_HOME /Applications/freesurfer source $FREESURFER_HOME/SetUpFreeSurfer.cshBut I am not sure where exactly I should add these lines. Do I need to edit the .csh file in Freesurfer. How should I do this? using Text Edit from apple would work?Thanks,Pablo
There should be a file called ".cshrc" in your home directory. Add the two lines to that file.
