Hi, This is the old documentation page for FSL version 4. We are now using FSL version 5, so please go to: http://fsl.fmrib.ox.ac.uk/fsl/fslwiki/ for the up-to-date documentation.

But I guess there is a small mistake in this page. We should use "_vox_p_tstat " file instead of " _vox_tstat " file ??? And anything except this is correct ??? THANKS Jie-Yu
