Very nice to see the Allen workflows plugged together this way. Thanks.

Principal component analysis gets 70% of the variance in the first 8 components. So starting with identical cells and growing in as identical conditions as a microsoft fortune could buy, we get to populations of cells where at least 30% of the variation is uncorrelated noise? I'm not sure whether I'm more impressed that the cells imposed that much order or more disappointed that the experimenters couldn't squeeze the population into a tighter cluster.
