This is described in the paper by Groppe and colleagues (2011):
Crucially, if you want to know when an effect starts to be significant,
you'll want to use the test with strong control of family-wise error rate
(the non-cluster-based test), not the cluster-based test (which only has
weak control of family-wise error rate, and doesn't license inferences
about when an effect starts to be significant).
This test is implemented in the Mass Univariate ERP Toolbox, which works
