Hi, Jenna-

That is true that many of those large radcor magnitudes are outside the brain in both cases. And inside the brain, many of the high magnitudes are tightly located in GM (though also some in local WM and CSF, too).

How does your corr_brain map look? That might also provide a sense of how much global motion is left in, in an important way.

And are the seedbased correlation maps (under vstat) pretty localized?

I wonder if you processed this subject with lower enorm (0.2, say) and outlier frac (0.05, say), does this change things? I believe that you have a tricky population that you are studying, so I understand that you have constraints/tradeoffs possibly forcing the choice of the less strict motion censoring. It is a tricky balance.
