Understanding reference building approach #12

Hi!

Really cool tool and web portal! I was trying to understand how you have been building references for Azimuth. A lot of what you did makes sense to me, but I stumbled across a line in the human BMMC reference script indicating an additional normalization step after individual batches had already been scTransformed.

See: https://github.com/satijalab/azimuth-references/blob/536fcbbf1a93f20a9f185d05b8d6cd456f3b5835/human_bonemarrow/scripts/integrate.R#L58

I was wondering why the second normalization step is needed here?

Thanks a lot!
