Briefly, samples were normalized with SCTransform (Hafemeister and Satija, 2019; 13,886 genes retained) and subsequently filtered to remove cells with high mitochondrial read contamination (>15%), low gene detection rate indicative of low-quality cells (<200), and high gene detection rate (>4,000) or high read count (>20,000) indicative of. It is obvious that the variance of counts is generally greater than their mean, especially for genes expressed at a higher level. FindClusters() 2.
