The wget application will handle poor connections, and retry if it is having problems. A failed download can be restarted by adding the -c flag to wget, which will cause it to continue from the point where a partial download stopped.

| ## === Additional group study data === ## There is an additional data set available upon which further group study analysis could be conducted. It is composed of the 40 subjects from which the tutorial's group study component was created. The data set is the full Freesurfer reconstruction of the 40 subjects (conducted using stable v3.0.2). It is 10.5GB compressed, and 18GB decompressed. It is named '''buckner_data-group_study.tar.gz'''. Also, there is the file '''buckner_data-raw_dicoms.tar.gz''', which, as indicated by the name, contains the original DICOM files for the ## subjects. Be sure to #[[http://surfer.nmr.mgh.harvard.edu/pub/dist/buckner_public_distribution.README.txt|read these notes.]] |
FreeSurfer Tutorial: Sample Data
The 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)(here is the md5sum)
- 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
fbert-feat.tgz & bert.recon.tgz - tutorial on the integration of FreeSurfer and FSL/FEAT
If you only want to get started with the basics of FreeSurfer, you need only download the bucker_data set. This will allow you to do the following tutorials:
Download using wget
The wget application is recommended, as some web browsers have difficulty downloading files greater than 4GB in size. Mac OS NOTE: use curl -O in place of wget.
Open a terminal, change to a directory where you know you have at least 100GB of space. To download, type:
wget ftp://surfer.nmr.mgh.harvard.edu/pub/data/buckner_data-tutorial_subjs.tar.gz & wget ftp://surfer.nmr.mgh.harvard.edu/pub/data/long-tutorial.tar.gz & wget ftp://surfer.nmr.mgh.harvard.edu/pub/data/fsfast-functional.tar.gz & wget ftp://surfer.nmr.mgh.harvard.edu/pub/data/fsfast-tutorial.subjects.tar.gz & wget ftp://surfer.nmr.mgh.harvard.edu/pub/data/fbert-feat.tgz & wget ftp://surfer.nmr.mgh.harvard.edu/pub/data/bert.recon.tgz & wget ftp://surfer.nmr.mgh.harvard.edu/pub/data/diffusion_recons.tar.gz & wget ftp://surfer.nmr.mgh.harvard.edu/pub/data/diffusion_tutorial.tar.gz &
The wget application will handle poor connections, and retry if it is having problems. A failed download can be restarted by adding the -c flag to wget, which will cause it to continue from the point where a partial download stopped. Notice the commands have the ampersand, so you can run all these commands at once (although the wget output will be hard to decipher, so an alternative is to run each without the ampersand in a separate terminal). Goto the Installation section below once the files are downloaded (this will likely take several hours). If you want to verify the md5sum, the md5sum for each of these files is found in files named *.md5sum.txt in this directory or get them this way:
wget ftp://surfer.nmr.mgh.harvard.edu/pub/data/buckner_data-tutorial_subjs.md5sum.txt & wget ftp://surfer.nmr.mgh.harvard.edu/pub/data/long-tutorial.md5sum.txt & wget ftp://surfer.nmr.mgh.harvard.edu/pub/data/fsfast-functional.md5sum.txt & wget ftp://surfer.nmr.mgh.harvard.edu/pub/data/fsfast-tutorial.subjects.md5sum.txt & wget ftp://surfer.nmr.mgh.harvard.edu/pub/data/fbert-feat.md5sum.txt & wget ftp://surfer.nmr.mgh.harvard.edu/pub/data/bert.recon.md5sum.txt & wget ftp://surfer.nmr.mgh.harvard.edu/pub/data/diffusion_recons.md5sum.txt & wget ftp://surfer.nmr.mgh.harvard.edu/pub/data/diffusion_tutorial.md5sum.txt &
You will want to ensure that these md5sum's match what you find when you run md5sum on your own local downloads. Mac OS NOTE: use md5 -r to get the same results as md5sum.
Installation
Once the files are downloaded, move the file(s) to the $FREESURFER_HOME/subjects directory, and uncompress and install with the following commands:
tar xzvf <filename>.tar.gz
Replacing of course <filename> with the name of each file downloaded. The downloaded .tar.gz files can then be deleted.
To setup the environment variable SUBJECTS_DIR to point to the tutorial data, type the following command or include in your .cshrc or .tcshrc file:
setenv TUTORIAL_DATA $FREESURFER_HOME/subjects setenv SUBJECTS_DIR $TUTORIAL_DATA/buckner_data/tutorial_subjs/
Note: If you are within the NMR Center, because the default $FREESURFER_HOME is shared, you will not be able to copy your data to $FREESURFER_HOME/subjects. Instead, copy the subject data to a location where you have space, and set the TUTORIAL_DATA and SUBJECTS_DIR environment variables to point to that. You may have to make adjustments throughout the tutorial wherever it refers to $FREESURFER_HOME/subjects (which is equivalent to your $SUBJECTS_DIR).
The tutorial will also instruct you to set the SUBJECTS_DIR when appropriate. The tutorial references the TUTORIAL_DATA var, which is the root directory containing the tutorial data (ie. the directories 'buckner_data', 'long-tutorial', 'fsfast-functional', etc.).
FSL-FEAT Tutorial Data
cd $SUBJECTS_DIR tar xvfz bert.recon.tgz cd /place/for/functional/data tar xvfz fbert-feat.tgz
