I would like to perform functional connectivity analysis within DMN of resting state datas from 2 groups. After preprocessing and band-pass filtering. I'm going to perform ICA and select the components having higest correlation within DMN (template from gift), and compared them between groups using two sample t-test in SPM with FDR.
Please let me know if my understanding is correct, or should i use MANCONVIAN to perform FC and comparison between groups.
I'll be grateful for any help.
