Hi,
I have resting state data for two groups - Group A (40 subjects, 6 mins, TR=2) and Group B (30 subjects, 8 mins, TR=1.5). I want to compare the two groups using ICA. Is this possible?? My understanding is to run Temporal concatenation ICA on each of the groups separately. Then identify components of interests to follow with DR.
1. Is my understanding correct? Is it possible to do it in this way?
2. Does the difference in total number of volumes and TR between groups affect the comparison? If yes whats the best way to account for it?
Thanks in advance for any feedback.
Thanks,
Brian
