FreeSurfer Tutorial Datasets
The full data for the tutorials consists of several data sets:
buckner_data-tutorial_subjs.tar.gz: the main 'recon-all' stream subject data processing (size: ~16GB uncompressed).
long-tutorial.tar.gz: the longitudinal tutorial (size: ~16GB uncompressed)
fsfast-tutorial.subjects.tar.gz & fsfast-functional.tar.gz: the FS-FAST tutorial data set (size: ~5.6GB uncompressed & ~9.1GB uncompressed, respectively)
diffusion_recons.tar.gz & diffusion_tutorial.tar.gz - the diffusion and Tracula tutorial 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.). 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.
