I'm not sure why this is happening. You could try it on fewer
subjects (e.g. 1) to make sure it's not something else about how the
job is specified. You'd only need the whole group following
segmentation (to create the template). Sorry I can't be of more help
here.

The short answer is yes. If memory serves the procedure in the DARTEL
guide walks you through registering the DARTEL template to MNI space,
and applying this transform to all the DARTEL-registered images. In
SPM8 there is a "normalise to MNI space" option that will take care of
this for you. You specify the flow fields and images for each
subject; the routine will compute the template -> MNI transform, and
combine this with the flow fields to get the rc* images into MNI space
(and also do the smoothing).
Best regards,
Jonathan
