image, normalised for skull size. It calls a series of FSL programs:
It first strips non-brain tissue, and then uses the brain and skull
images to estimate the scaling between the subject's image and
Talairach space. It then runs tissue segmentation to estimate the
standard space. It then runs tissue segmentation to estimate the
volume of brain tissue, and multiplies this by the estimated scaling
factor, to reduce head-size-related variability between subjects.
