Old issue: Documentation of ROI sets

"A communication with another colleague made me realize we should probably note what the different ROI sets are and where they come from. The note itself shouldn't take more than 30 minutes to write, however, it may take much longer to pull the relevant citations."

Thanks, @ericfeczko !

We have something like that from an old document. Is this what you're hoping for?
