Hi Luca,
in case you want to compare activations across subjects, you may want to
try normalization instead of coregistration (and, while you're at it,
spm5 instead of spm2 :). Coregistration is meant to allow comparing
images of different modalities from one subject (i.e., coregister an EPI
to a structural image). Huge amounts of information on either procedure
can be found in the archives at

Best,
Marko
