A little confused here...
In my analysis, Independent components from ICA analysis for each subject per session(3 totally) is one sample T tested using SPM. I got 15 subjects contrast images per session. If I want to check the subject differences or similarities within a session, can I do another 1 sample T test on the contrast images? if yes, what exactly does this second stage T test give?
Apologize of the very fundamental statistical question.
