Hi All,

After reading the wiki (http://www.fieldtriptoolbox.org/faq/how_can_i_test_an_interaction_effect_using_cluster-based_permutation_tests <http://www.fieldtriptoolbox.org/faq/how_can_i_test_an_interaction_effect_using_cluster-based_permutation_tests>), it appears that I cannot do a cluster based permutation test on a set of data I have because of the fact that I have two between subject factors (genotype and sex). There has been a lot of discussion on the mailing list about how to run these kinds of analyses, but they have always (or at least what I could find), been about data set containing only 1 between subjects factor. As such, I have a question in two parts A) could I look at the data with a proper test of the between subject factors, and the within subject factor AND their interaction using a permutation test that use holms or bonferroni correction (though I would probably use holms because of bonferroni being to conservative) B) should I set this up by either i) testing geno, sex and their interaction separately like I think the wiki suggests above or ii) try and use the cfg.cvar input as previously suggested else where on this discussion list (though again that was for data with only 1 between subject variable)?
