Important Note: When processing a group of subjects for your study, it is essential to process all your subjects with the same version of FreeSurfer, on the same OS platform and vendor, and for safety, even the same version of the OS. While we continue to work to ensure that results match across platforms, there are none-the-less system-level libraries that are OS dependent. An exception to this rule is that you may view and edit files across any platform or version, and run some post-processing tools (outside the recon-all stream) if you check with us first (for instance you may run the longitudinal processing with newer versions).

A license key must be obtained to make the FreeSurfer tools operational. Obtaining a license is free and comes in the form of a license.txt file. Once you obtain the license.txt key file, copy it to your FreeSurfer installation directory. This is also the location defined by the FREESURFER_HOME environment variable.
