Is There a Grace Image for Whole Brain?

With new technology we can use a much larger field of view. With low flip anglei will have maybe, i think on the order o mayb be 20 times larger volume coverds than we did in these early experiments. I've often thought about how do you average across subjects with this dataw? Any ideas and howls? Are we just going to get inferences about single subjects deep imaging in general iso there? Or can we compare across subjects in any meanful way? What's the best way of doing that?
