Hi Eugene,
Thanks for your reply. I performed TICA on the all the subjects' data (as suggested by Christian Beckmann in a previous post). Basically we have a block design (1 session) with 4 different stimuli in 20 subjects. We are looking to find a common component for the 4 stimuli types in all subjects and to compare the connectivity of the component in each of the 4 conditions.
Massih
