Hi Mark,
OK I think I got it now.
If I want to contrast between two sessions of resting state (session 1 and 2; within subject), should I run melodic with the data from both sessions and then run dual_regression specifying that there is 2 sessions using the design.mat and design.con. Since I have 12 subjects in my group, the design.mat would be a 1 column of : -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 -1 1 1 1 1 1 1 1 1 1 1 1 1 and the design.con would just 1. And of I want to test the reverse post-pre I'd change the desing.con to -1
Is this correct?
Thanks for your help,
Pat
