Dear Gonzalo,
We do not recommend using the current version of fsl_anat with an already brain-extracted image, but you can try it with a brain-extracted image if you like. It might work, as the brain extraction steps within it are likely to do nothing, although problems may occur in registration, where the standard reference images will not match.
All the best,
Mark
