| 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). | <<TableOfContents>> |
| Line 7: | Line 7: |
| 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]. |
== FreeSurfer Tutorial Datasets == ## The data set for the Freesurfer tutorials comes in two forms, a "Lightweight" version and a "Full" version. |

| The troubleshooting tutorials, in the section [wiki:Self: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 "Lightweight" version contains only the files required to run the commands of the !FreeSurfer tutorial. It has all the required input and output data, but lacks the other files that would normally be present when performing a recon. People who just want a quick easy way to run the commands in the tutorial should download this data set. |
| Line 13: | Line 12: |
| The group study [wiki:Self:FsTutorial/GroupAnalysis analysis] and [wiki:Self: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. | ## * The "Full" version contains all the files that would normally be present when performing recons. Because of the numerous subjects involved with the tutorials, the full data set is quite large (~60Gigs). People who want to go into more depth than that which is covered in the tutorials should download this data set. |

| Once a file is downloaded, move the file to the $FREESURFER_HOME/subjects directory, and uncompress and install with the following command: | ## == Lightweight version == ## Use the following link to download the lightweight version of the tutorial data: ## . [[ftp://surfer.nmr.mgh.harvard.edu/pub/data/tutorial_data.tar.gz|tutorial_data.tar.gz]] ## Once the download is complete, uncompress the data file - this usually this can be done by simply double-clicking. In order to do the tutorials, users must define an environment variable called '''TUTORIAL_DATA''' which is set to the location of the extracted data. 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 ## }}} ## You are now ready to start the [[Tutorials|Freesurfer tutorials]]. ## == Full version == The size of the data for the freesurfer [[Tutorials|tutorials]] is quite large, so it consists of several sets: || '''Download''' || '''Description''' || '''Size''' || || [[ftp://surfer.nmr.mgh.harvard.edu/pub/data/tutorial_data_core.tar.gz|Core Data]] || The core tutorial subject data || 16.8 GB || || [[ftp://surfer.nmr.mgh.harvard.edu/pub/data/tutorial_data_functional.tar.gz|Functional Data]] || The !FsFast functional tutorial data || 18.1 GB || || [[ftp://surfer.nmr.mgh.harvard.edu/pub/data/tutorial_data_diffusion.tar.gz|Diffusion Data]] || The diffusion and tracula tutorial data || 4.3 GB || || [[ftp://surfer.nmr.mgh.harvard.edu/pub/data/tutorial_data_longitudinal.tar.gz|Longitudinal Data]] || The longitudinal tutorial data || 15.5 GB || If you only want to get started with the basics of !FreeSurfer, you need only to download the core data set.

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.).

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 only want to get started with the basics of FreeSurfer, you need only 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 run from a terminal window.
cd /path/to/your/tutorial/dir tar -xzvf </path/to/downloaded/file.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.
