Hi Elena, I am running a rsfMRI analysis (3 different groups) and I have some > questions about the randomise tool. Do I have to use the > exchangeability-block (design.grp) file? > No, not necessary here. I created the design and contrast matrix but I am also confused about > covariates and demeaning.I have 3EV's (one per group) and 2EV's (age & > gender). I demeaned the age and gender regressors. Is it correct? > Looks fine to me. The sex for one of the subjects is marked as -3.500000e-01, instead of -3.400000e-01 as the others, but this is so small that I doubt it will make any difference. All the best, Anderson
