Betreff: [FieldTrip] Cluster-based permutation: Interactions & Alpha adjustment

Dear community,

I am using the cluster-based permutation test for statistical evaluation of my data. Besides main effects I also test the interaction between them. When following up on a significant interaction with further permutation tests I feel I should correct my alpha level for multiple comparisons. Is that correct?
