Hi, I would start by reading the randomise manual carefully to make sure you understand the different files output by randomise, then have a careful look at these in FSLView to make sure that you are actually getting significant results (>0.95 in the _corrp file). You can extract location information about significant clusters using the "cluster" program. Cheers.
