Hi,
Sorry I used to use FSL but have to run some data in SPM...
Does anyone know that, in FSL, if I want to know activations correlated with a behavior score in a group of subjects, I must setup 2 EVs: group mean (all 1s) and behavior score (but must be demeaned) in higher-level model.
In SPM, do I have to setup 2 EVs? Or can I just use one EV: behaviour score (and no need to demean it)?
Thanks
Mark
