Hello,
We are trying to analyze the resting state data using group ICA (melodic and dual regression). I have one question regarding the group ICA.
Do the groups in Melodic need to be balanced in order to find the common spatial independent components?
In our case, we have 14 controls, 15 early patients and 15 advanced patients. Do we need to randomly choose 7 early patients and 7 advanced patients to match the 14 controls ( 14 patients vs 14 controls) for Melodic?
Or we could simply run Melodic with all subjects (14 controls, 15 early patients and 15 advanced patients)?
Thank you very much for your help.
