Hi Paul,

Thank you so much for your rapid response! And yes, perhaps this is a question about properly using 3dClusterize!

I am wondering if there is a way to see statistics associated with the significance of a cluster, i.e., a t-value, after using 3dttest++ with ETAC.

When I run the 3dClusterize script below, I get the following output. Is there something that I am missing in order to have t-values output here as well? Or another way that I can look at t-values for each cluster?

Thank you so much for your help!

Warmest Regards,
Katie
