Hi there,<br><br>I just installed freesurfer onto a mac os x.  My computer seems to default to bash, so I created a .bashrc file in my home directory and added the lines:<br><br>export FREESURFER_HOME=/Applications/freesurfer<br>
source $FREESURFER_HOME/SetUpFreeSurfer.sh<br><br>but just in case I also created a .cshrc and added the c shell version of that code.  I also created the .license file as per the installation instructions.  Then I opened up the terminal, in bash, and did the export and source thing again.  I also updated the SetUpFreeSurfer file so that it has the correct path: /Applications/freesurfer.  However, when I try to test the installation and type in recon-all -s bert -autorecon1 (i have to use sudo as well bc it keeps telling me i don&#39;t have write permission) I always get back FREESURFER_HOME: Undefined variable.  I&#39;ve seen several other people post this same problem to this forum in the past but no one has ever posted a response that I can see.  I tried reinstalling, and typing in the command from different directories, and sourcing again, but I always get back the same response.  The really frustrating thing is, when I type echo $FREESURFER_HOME I get back /Applications/freesurfer which is correct!  Any thoughts on what I&#39;m doing wrong here?<br>
<br>Thanks in advance.<br><br><br>
