Both options take the same kind of argument; it is the cluster-
forming threshold and is in the units of the raw t-statistic image
formed by randomise. So for example if you enter 2.5 then clusters
above t=2.5 will be formed and tested for significance on the basis
of their extent (-c option) or "mass (-C option).
Cheers.
