Description
mkbrainmask-sess creates a binary mask of the brain from an input functional volume. It uses the FSL Brain Extraction Tool (BET). By default, the input is the f volume from the first run of the session from the bold directory. The input volume can be changed with the -funcstem option; the run can be changed with the -run option; and the functional subdirectory can be changed with the -fsd option. The output will be placed in a directory called masks under the FSD. The stem will be brain unless changed with the -maskstem option. The only real parameter is the threshold (controlled with the -thresh option). The absolute threshold is set to thresh times the global mean.

Methods Description
A brain mask was generated using the Brain Extraction Tool (BET) which is available from the FSL software library (www.fmrib.ox.ac.uk/fsl) (Smith 2002).
