Hello Experts,
I’d like to determine which of my subjects show significant activation in the 3 ICs which withstood FWE correction (after group rs-fMRI analysis in Melodic followed by dual regression) in the corrp files followed by correction for multiple comparisons.
I know that the individuals Z maps and ICs for every individual are in the dr_stage_2 files from dual regression (ie dr_stage2_ic0XXX and dr_subject0000X). I’ve been looking closely at these, and realize that it would be hard for me to say at what level I would threshold them to convince myself which of them actually has significant activity in the areas of the 3 ICs from group comparison. Am I way off here? Is this even possible? My goal is to look back and say, even if I was blinded from knowing which of these subjects has high or low IQ, I could look at these 3 ICs from that individual and make an educated guess, and be right more often than not. Or at least report how often I was wrong for the sake of showing what doesn’t work.
Thank you in advance,
Varina Wolf
