FreeSurfer Tutorial Datasets
The size of the data for the freesurfer tutorials is quite large, so it consists of several sets:
Download |
Description |
Size |
The core tutorial subject data |
16.8 GB |
|
The FsFast functional tutorial data |
18.1 GB |
|
The diffusion and tracula tutorial data |
4.3 GB |
|
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.
