Hi,
I can see from the mailing list that there are lots of ways to run VBM when you have multiple scan sessions, e.g. performing a subtraction or halfway registration. Is it possible though to control for GM at first session, when looking at differences between groups in a second session? I'm interested in whether an intervention resulted in different effects across groups for the second scan session, but these groups should have been indistinguishable in the first session.
Thanks for your advice.
Sam.
