Cluster Threshold for post-hoc t-tests

Hi AFNI Experts:
I ran 3dMVM to analyze my data, which includes three groups. Afterwards, I ran 3dFWHMx and 3dClustSim. Can I use the same cluster threshold for the post-hoc t-tests?
Thanks,
Lisa

Lisa, the cluster-based approach as a band-aid for mass univariate modeling would be equally applicable among all the post hoc inferences since they share the same spatial smoothness parameters.
