Scanpy: Differential expression. ¶. Once we have done clustering, let's compute a ranking for the highly differential genes in each cluster. Differential expression is performed with the function rank_genes_group. The default method to compute differential expression is the t-test_overestim_var. Other implemented methods are: logreg, t-test ...
WebCensus - demo ScanPy rank_gene_groups¶.

WebTo identify differentially expressed genes we run sc.tl.rank_genes_groups. This function will take each group of cells and compare the distribution of each gene in a group against the distribution in all other cells not in the group. Here, we will use the original cell labels given by 10x to identify marker genes for those cell types.
