= FreeSurfer License =

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 (i.e. the top-level directory, usually called "freesurfer"). This is also the location defined by the $FREESURFER_HOME environment variable, which is described later in the [[SetupConfiguration|setup and configuration section]].
