Hi Maedeh,

Instead of changing your .bashrc, you can just execute the following lines when you want to switch versions (or place them into a bash script that you load with "source your_script").

export FREESURFER_HOME=/path/to/your/desired/freesurfer/directory source $FREESURFER_HOME/SetUpFreeSurfer.sh

Cheers, Malte

Hi Maedeh,

You can. But you will to name them different and change the .bahsrc file every time you use one or the other.

Hope this helps, Rosalia

Dear FreeSurfer experts, I wonder if I can install two versions of FreeSurfer (the latest one and an older one) on one system at the same time. Thanks more.
