FreeSurfer Tutorial Datasets

The size of the data for the freesurfer tutorials is quite large, so it consists of several sets:

Download

Description

Size

Core Data

The core tutorial subject data

16.8 GB

Functional Data

The FsFast functional tutorial data

18.1 GB

Diffusion Data

The diffusion and tracula tutorial data

4.3 GB

Longitudinal Data

The longitudinal tutorial data

15.5 GB

If you just want to get started with the basics of FreeSurfer, you only need to download the core data set. This will allow you to run the following tutorials:

Installation

Once the dataset(s) have been downloaded, uncompress and install with the following command:

cd /path/to/your/tutorial/dir
tar -xzvf /path/to/downloaded/data.tar.gz

Configuration

In order to run 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=/path/to/your/tutorial/dir
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.
