How to do hierarchical cluster in afni?

Dear afni experts,

I wonder that if afni could do the hierarchical cluster to get a specified number of rois. The reason i wanna do this is i wanna do power-law fit using degree centrality data, i tried each voxel value(correlation coefficient, threshold > 0.3 ) in the whole brain by using 3dmaskdump, but the result does not seem good.So i wanna try it in this way.I hope to get your answer, thanks a lot.

It may not have all of the features you need, but have you seen 3dStatClust?

Okay, I’ll try that command, thanks a lot.
