Dear SPMers,
I have a question on the group analysis. We have two treatments (A and B)
with both pre- and post-treatment fMRI data. Now we are to analyze the
difference between treatment A and treament B, that is, (A_post - A_pre) -
(B_post - B_pre) .
Is there anybody who can provide some guidelines on how to perform such
analysis in SPM? It is better if the steps can be described briefly.
best wishes,
Vincent
