Hi Shary, Jorge,
owing to the more elaborate matching of the probability maps to the
image implemented in spm5, the adverse effect of using an adult template
for pediatric analyses may be less pronounced.
HOWEVER, as not only shape differences occur but also differences in
local tissue concentration, I would still expect large differences
especially in the regions where children differ most from adults
(frontal and parietal lobes). One could probably use my old CCHMC_2
templates in spm5, although I have not had time to try this.
Best,
Marko
