fMRI Angst

Hi Together with Andre and Nikos, we have collected some potentially very interesting results via an fMRI study on task switching. The issue is this. When we do group analyses with cluster correction, 3 very large blobs are found in contrasting cond 1 with cond 2. However, in playing with fslview it is clear that within these blobs there are more interesting localised islands of activity. My dilemma is this if we simply report the cluster-corrected blobs that is okay but what I really want to discuss are these other ROIs. So how do I get this published and satisfy the statisitcal reviewer? I cannot do a simple a priori ROI analysis because some of the conditions are relatively novel and we cant predict where the ROIs might be. We can do this via email or I can talk about this at YNiC next week perhaps?
