Dear fellow CONN-enthusiasts,

My problem:
I am comparing resting state fMRI functional connectiviy change of 2 groups (control & intervention) between 2 sessions (time 1 & time 2). Now I would like to know if the influence of a factor ("performance") on functional connectivity differs between the groups. Performance is a metrical numerical variable with a range from 0 to 3.
My goal is to know the influence of group and performance on functional connectivity.

Can somebody help me? How can I do that?

Cheers
