"WebCell cycle variation is a common source of uninteresting variation in single-cell RNA-seq data. To examine cell cycle variation in our data, we assign each cell a score, based on its expression of G2/M and S phase markers. After scoring each gene for cell cycle phase, we can perform PCA using the expression of cell cycle genes. " - Scanpy subset cells
