Hello,
in reply to your questions:
> 1.Under what circumstances does the create template have to be performed
> separately for each group(yielding 2 DARTEL templates,One for each group)
Under the (admittedly very unlikely) condition that you do NOT want to
directly compare the groups (as otherwise, the effect of different group
and different template cannot be disentangled).
> 2.Under what circumstances do I create a single DARTEL template from all
> the subjects from both groups(40) ?
Under all other conditions :)
Cheers
Marko
