Hi, I have questions about setting my data for rsfMRI analysis in CONN

Hi!
I have had problems for setting my MRI data in CONN.
 
I have two groups; sham stimulation group, real stimulation group.
I have two conditions within subjects; pre-stimulation, post-stimulation.
I wanna compare the functional connectivity between groups and between conditions.
How can I set up my data in CONN?
 
Sincerely yours.
