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. WebEvaluating clustering. Intuitively, we can see from the plot that our value of k (the number of clusters) is probably too low.. This dataset has "ground truth" cell type labels available.
