Dear FSL Experts,
If I set both -corrmod and -corrcon options of PALM for my analysis, correcting the results across modalities and contrasts, and use -logp option, saving the output p-values as -log10(p), which value for threshold should I choose? For example, if I have 2 groups (patients and normal controls), 8 resting state networks (modalities) for analysis, testing two tails differences (patients > normal controls and patients < normal controls), since I already use PALM to correct for p values across modalities and contrasts, should I just use -log(0.05) = 1.3 as the threshold number for significant clusters? Or it's still necessary to use the number of -log(0.05/8*2) = 2.5?
Thank you very much.
