can you give us the details of the protocols? And are you talking about 2 different acquisitions on the same subject, or two groups of subjects with different acquisitions? If the latter then your groups must be balanced in terms of # of subjects for each acquisition type.

Hello, Group
I have two set of images acquired with different imaging protocols (e.g., TRs and bandwidth are different). Can I poll them together for the analysis?
I saw in the email list that some groups reported problems in generating the average of images with different TR for the group analysis. I do not seem have problem to make average include all the images.
But is the result acceptable if the images acquired with multiple protocols?
Thank you
