Dear FSL'ers,
I want to study voxel-wise differences in R2* for a single subject between two conditions. I have four R2* maps per condition, so that's a total of 8 measurements per voxel.
My null hypothesis is that there are no differences between both conditions, so the permutations should be such that each of the 8 runs can be labeled "A" or "B", as long as there are 4 of each type.
What should be the design matrix and exchangeability block labels file?
Thanks!
-Pablo
