FreeSurfer Tutorial: Sample Data

A public distribution data set is available to run the tutorials. It contains 40 subjects, and occupies about 21G of disk-space. The data set is divided into two files: the data for the troubleshooting examples (7GB), and the data for the group study analysis (14GB).

The files are available from the [ftp://surfer.nmr.mgh.harvard.edu/pub/dist distribution site], and are called [ftp://surfer.nmr.mgh.harvard.edu/pub/dist/buckner_data-tutorial_subjs.tar.gz buckner_data-tutorial_subjs.tar.gz] and [ftp://surfer.nmr.mgh.harvard.edu/pub/dist/buckner_data-group_study.tar.gz buckner_data-group_study.tar.gz].

The troubleshooting tutorials, in the section [wiki:FsTutorial/MorphAndRecon Morphometry and Reconstruction], require the [ftp://surfer.nmr.mgh.harvard.edu/pub/dist/buckner_data-tutorial_subjs.tar.gz buckner_data-tutorial_subjs.tar.gz] download.

The group study [wiki:FsTutorial/GroupAnalysis analysis] and [wiki:FsTutorial/Visualization visualization] tutorials require the [ftp://surfer.nmr.mgh.harvard.edu/pub/dist/buckner_data-group_study.tar.gz buckner_data-group_study.tar.gz] download.

Once a file is downloaded, move the file to the $FREESURFER_HOME/subjects directory, and uncompress and install with the following command:

tar xzvf buckner_data-XXXXXX.tar.gz

where XXXXXX is either tutorial_subjs or group_study.

The downloaded file can then be deleted.

To setup the environment variables SUBJECTS_DIR and SUBJECTS to point to the group study tutorial data (for use in the tutorial sections group study [wiki:FsTutorial/GroupAnalysis analysis] and [wiki:FsTutorial/Visualization visualization]), type the following command or include in your .cshrc or .tcshrc file:

source $FREESURFER_HOME/subjects/buckner_data/group_study/scripts/setup_subjects.csh
