Hey Steve,
Thanks for the quick reply and for the correction. But, when comparing data within session, do you not need to worry about how you register the series to one another? Is it sufficient to just coregister each to the T1 (or even MNI) or might this bias the result to favor one session over the other? An EPI collected closer to the T1 might require less alignment than one collected later due to head motion.
Cheers,
Cameron
