Dear SPMers,
I’ve analyzed differences in connectivity between 2 groups using Donald McLarens GPPI toolbox. My VOI was defined on the group contrast (groups differed in insula activity). Now I want to test for hypothesis driven group differences in connectivity between the insula-VOI and a second structurally defined ROI. In a first step I defined my structural VOI file in my master template – however results were the same than in the unrestricted analysis. Which further steps do I have to implement to investigate differences in connectivity between the two VOIs?
Thanks in advance & best regards,
Ben
