FreeSurfer can be accessed from most computers on the Martinos network. This page will show you how to access the FreeSurfer program, and points you towards some tutorials to get you started using it.

Accessing FreeSurfer

First, consider if you need access to a stable or development version of FreeSurfer. If you are not sure you probably want to use the stable version. The development version contains new and untested features.

Copy and paste a command below into your terminal:

Stable:

source /usr/local/freesurfer/nmr-stable60-env 

Development:

source /usr/local/freesurfer/nmr-dev-env 

To ensure that worked, type  freeview  into the command prompt, press enter, and see if FreeView opened. FreeView is a tool that comes with FreeSurfer - it lets you look at the data FreeSurfer creates
