No you don't - you generate templates based on the statistical
assesssment of a large sample (this is what we termed "radically
different" approach to creating templates :)
Either way, the problem remains: if you add subjects and want to add
their influence to the template and use that to process them, this will
be, in effect, a new study as you ue new reference data. The difference
might be negligible, but will be there nonetheless. So in other words,
you can either wait until you have all subjects and only process them
then based on the final template or you process them at intermediate
milestones, but will have to reprocess them in the end. I see no other
way. Not sure if that was the question, though :)
