Important note¶

Freesurfer is known to produce differing results when used across platforms. See http://journals.plos.org/plosone/article?id=10.1371/journal.pone.0038234 for details. We recommend that you run all of your analyses for any given study on the same operating system/hardware combination and record details of these as part of your results.

Testing¶

No formal test suite was found. A set of commands to try were suggested at https://surfer.nmr.mgh.harvard.edu/fswiki/TestingFreeSurfer (Accessed November 6th 2015)

The following were tried

freeview -v $SUBJECTS_DIR/bert/mri/brainmask.mgz -v $SUBJECTS_DIR/bert/mri/aseg.mgz:colormap=lut:opacity=0.2 -f $SUBJECTS_DIR/bert/surf/lh.white:edgecolor=yellow -f $SUBJECTS_DIR/bert/surf/rh.white:edgecolor=yellow -f $SUBJECTS_DIR/bert/surf/lh.pial:annot=aparc:edgecolor=red -f $SUBJECTS_DIR/bert/surf/rh.pial:annot=aparc:edgecolor=red

Installation notes¶

These are primarily for administrators of the system. The github issue for the original install request is at https://github.com/rcgsheffield/sheffield_hpc/issues/164

Freesurfer was installed as follows

wget -c ftp://surfer.nmr.mgh.harvard.edu/pub/dist/freesurfer/5.3.0/freesurfer-Linux-centos6_x86_64-stable-pub-v5.3.0.tar.gz
tar -xvzf ./freesurfer-Linux-centos6_x86_64-stable-pub-v5.3.0.tar.gz
mv freesurfer 5.3.0
mkdir -p /usr/local/packages6/apps/binapps/freesurfer
mv ./5.3.0/ /usr/local/packages6/apps/binapps/freesurfer/

The license file was obtained from the vendor and placed in /usr/local/packages6/apps/binapps/freesurfer/license.txt. The vendors were asked if it was OK to use this license on a central system. The answer is ‘yes’ - details at http://www.mail-archive.com/freesurfer@nmr.mgh.harvard.edu/msg43872.html

To find the information necessary to create the module file

env >base.env
source /usr/local/packages6/apps/binapps/freesurfer/5.3.0/SetUpFreeSurfer.sh
env > after.env
diff base.env after.env

The script SetUpFreeSurfer.sh additionally creates a MATLAB startup.m file in the user’s home directory if it does not already exist. This is for MATLAB support only, has not been replicated in the module file and is currently not supported in this install.

The module file is at /usr/local/modulefiles/apps/binapps/freesurfer/5.3.0
