I am trying to run a repeat measures 2x2 anova and correct for multiple comparisons all in one, a la 3dttest++ -ClustSim. Is there any functionality to do this yet? I am using 3dANOVA3 to run the anova.

If not, which method is best for permutation testing to correct for multiple comparisons in a repeat measure 2x2 ANOVA in afni?
