p.s. you would be better off if you had the same proportion of patients and controls with each sequence. Matching the numbers within one sequence and not the other doesn't really help

Hello list,
I have a group of subjects (4 patients and 8 controls) in which one MPRAGE sequence was used and another group of subjects (2 patients and 2 controls) where a diffent MPRAGE was used. Both groups were acquired in the same scanner. For each subject I have two anatomical sequences and I'm working with the average dataset. My question is can I put both groups together for comparision?
I've thought about this and I can't really be sure... I was thinking that since for group 2 the number of acquisitions is balanced maybe the overall impact of different sequences won't be significative... Patients and subjects are age-matched in both groups.
Please, any advice will be greatly appreciated!
