Hello, Meghen,
For each contrast, Randomise calculates how many unique permutations there are for the design ( e.g. for a group difference contrast, a permutation that swaps two subjects within a group is redundant as it will not alter the value of the test statistic ). For your design there are only 70 unique permutations possible, this is less than your requested number of permutations so randomise performs an exhaustive test.
Many Regards
Matthew
> Hi Matthew, thanks for responding. It's not stalling at any given permutation. Here's the output I'm getting (sorry for the length):
