Hello Amy,
DARTEL is primarily a tool the serves inter-subject coregistration of
e. g. GM and WM maps. Such coregistration is e. g. needed for VBM.
It is not primarily a segmentation instrument, rather, a segmentation step
has to be performed *before* you forward your images
to DARTEL. For this segmentation step there are several options (segment,
or the new segment function in SPM8) - please refer to the manual to see
which SPM functionality is best for your question.
