2nd level contrast
Dear All,

We have  1 session for control group and 2 sessions(pre and post treatment) for Patient group.

We want to compare functional connectivities (seed to voxel) among those three dataset
(control-prePatient, control-postPatient, prePatient-postPatient).

CONN allow us to define 1 or 2 sessions for a subject (with session invariant structural image).
We defined 2 conditions: preRest & postRest for comparison in the second level anaysis.

One session of Control group defined for both conditions, while two sessions of Patient group defined separately for conditions.

But we have problem while adding effect of rest at the denosing step. There is double "Effect of rest" for control group (pre and postRest) due to the our condition definition style.
Do you have any advise for this type of comparisons?

Is there a contrast definition at the second level for comparing control(preRest) vs. patient(postRest)?

Best Regards.
Ali
