are you sure they are being ignored? The -s option only supplies the first estimate for the tissue type means and these are subsequently refined by the FAST model. If you don't supply initial tissue type means FAST will use an "automatic" initialisation and it is not unlikely that this initialisation leads to the same ultimate solution.
