FreeSurfer Course Setup
This purpose of this page is to describe how one would go about setting up laptops (or workstations) for a Freesurfer course.
Laptops/workstations should have an Operating System and hardware which meet or exceed the recommended System Requirements for running freesurfer.
- Laptops/workstations should have internet access. (For following course tutorials and performing last minute updates of the data set)
- In addition to the listed System Requirements, laptops should have 17" screens to facilitate viewing of images on the screen.
Laptops/workstations should have Freesurfer v6 installed.
Laptops/workstations should have Matlab runtime version 8.3 installed (no license required). (Matlab is required for the FSFAST only, and the commands requiring Matlab have been marked and can be skipped because the output data has already been provided. So Matlab is not an absolute requirement.)
A prepackaged tarball has been created which contains Freesurfer v6, FSL, and the Matlab runtime, (along with a custom .bashrc file), so that all these packages can be installed in one step. This tarball can be downloaded from the following link:
See the Data page for intructions on how to download and install the various datasets required to do the tutorials. Because some of the data files are modified during the tutorials, each workstation will need access to its own version of the data set.
A .basrch file comes with the Freesurfer/FSL/Matlab runtime package from above. The course administrator should link either link the users .bashrc to the one in the freesurfer installation:
cd ~ ln -s freesurfer/.bashrc
or copy its contents into the users already existing .bashrc file:
## set deflaut location of freesurfer FSHOME=~/freesurfer ## Set location of tutorial data export TUTORIAL_DATA=~/tutorial_data ## Set location of FSL (Required for Diffusion and TRACULA tutorials only) export FSLDIR=$FSHOME/fsl_507 ## Set location of Matlab and other Matlab/FSFAST related variables (Required for FSFAST tutorial only) export FS_MCRROOT=$FSHOME/MCRv83/v83 export LD_LIBRARY_PATH="$LD_LIBRARY_PATH":"$FS_MCRROOT/runtime/glnxa64" export LD_LIBRARY_PATH="$LD_LIBRARY_PATH":"$FS_MCRROOT/bin/glnxa64" export LD_LIBRARY_PATH="$LD_LIBRARY_PATH":"$FS_MCRROOT/sys/os/glnxa64" export LD_LIBRARY_PATH="/usr/lib/x86_64-linux-gnu":"/lib/x86_64-linux-gnu":"$LD_LIBRARY_PATH" export FS_SPMREG_USE_BIN=1 export FS_MKCON_USE_BIN=1 export FS_SXA3_USE_BIN=1 ## Source freesurfer export FREESURFER_HOME=$FSHOME source $FREESURFER_HOME/SetUpFreeSurfer.sh
Make sure the TUTORIAL_DATA environment variable is set correctly by typing ls $TUTORIAL_DATA in a terminal window. You should see the output below:
$> ls $TUTORIAL_DATA buckner_data fsfast-functional diffusion_recons fsfast-tutorial.subjects diffusion_tutorial long-tutorial
Once you verify freesurfer is sourced correctly and the TUTORIAL_DATA environment variable is set correctly, the best and most reliable way to test your setup is simply to run thru one or more of the tutorials.
