To install FreeSurfer from tar files
1. Obtain a license key from http://surfer.nmr.mgh.harvard.edu/registration.html or from a previous installation. If you are using a previous installation, the license file should be freesurfer/.license.
3. Enter the command:
tar xvfz DISTDIR/freesurfer.tar.gz
This will create a directory called freesurfer, in which will be the following files:
INSTALL -- this fileBR license.freesurfer -- license agreementBR freesurfer.tar.gz -- FreeSurfer treeBR talairach.tar.gz -- MNI 305 talairach brainBR bert.raw.tar.gz -- FreeSurfer tutorial dataBR bert.func.tar.gz -- FreeSurfer functional tutorial dataBR bert.recon.tar.gz -- reconstructed FreeSurfer tutorial dataBR average7.tar.gz -- contains average labels for checking spherical morphBR
4. The default subjects directory (the directory in which your subjects' data will be placed) is freesurfer/subjects. You may wish set to up your installation differently, e.g. if you have a large external hard drive you want to use for subject data. See the [wiki:SetupConfiguration 'Setup and Configuration'] section for details. Regardless, cd into your subjects directory (the default is called 'subjects', located within the freesurfer installation directory) and enter the commands:
tar xvfz DISTDIR/average7.tar.gz BR tar xvfz DISTDIR/bert.recon.tar.gz tar xvfz DISTDIR/talairach.tar.gz
This will populate your subjects directory with 'average7', the sample data set 'bert', and the MINC atlas subject 'talairach'.
FreeSurfer uses some of the tools developed at the Montreal Neurological Institue (MNI) (http://www.bic.mni.mcgill.ca) to align antomical volumes (using minctracc) and to compute the Talairach transform (using mritotal). You must have the MNI tools installed to be able to access this functionality through FreeSurfer.
