Hello,
I had a quick question about inputs to randomise for fMRI. I know that normally you use the second-level COPEs as inputs. I was wondering whether it would be appropriate to instead use the t- or z-stat images from the second-level fixed effects analysis. It seems to me like this would allow you to account for differences in intra-subject variances when you do the permutation test. Please correct me if I'm wrong or missing something...
Thanks,
Ian
