FreeSurfer Tutorial Datasets

The full data for the tutorials consists of several data sets:

Also, if you only want to get started with the basics of FreeSurfer, you need only download the buckner_data set. This will allow you to do the following tutorials:

Installation

Once the dataset(s) have been downloaded, uncompress and install with the following command run from a terminal window.

tar -xzvf <filename>.tar.gz

Replacing <filename> with the name of the file downloaded. The downloaded .tar.gz files can then be deleted.

Configuration

In order to do the tutorials, users must define an environment variable called TUTORIAL_DATA which is set to the root directory containing the extracted data (i.e. the directories 'buckner_data', 'long-tutorial', 'fsfast-functional', etc.). The tutorials make frequent use of the TUTORIAL_DATA environment variable and it need to be set properly for any of the tutorials to work. For example:

export TUTORIAL_DATA=/home/username/Downloads/tutorial_data
ls $TUTORIAL_DATA

buckner_data                    fsfast-functional
diffusion_recons                fsfast-tutorial.subjects
diffusion_tutorial              long-tutorial

If you see something similar to the above output (you may not have downloaded all the tutorial data sets) you are now ready to start the Freesurfer tutorials.
