Hi Matthew,
Thanks for the info. Can I ask (ahead of rerunning randomise) what the format of the -N text file output is? Do I get the maximum cluster size value from each of my permutations?
I guess I can then order them in size from smallest to largest, and move to the value appearing 95% of the way through in order to determine the threshold cluster size.
Cheers,
Donal
