WebMar 27, 2024 · To identify canonical cell type marker genes that are conserved across conditions, we provide the FindConservedMarkers () function. This function performs differential gene expression testing for each dataset/group and combines the p-values using meta-analysis methods from the MetaDE R package. WebMay 23, 2024 · Positive values indicate that the gene is more highly expressed in the first group. pct.1 : The percentage of cells where the gene is detected in the first group pct.2 : The percentage of cells where the gene is detected in the second group p_val_adj: Adjusted p-value, based on bonferroni correction using all genes in the dataset.

If so, this could throw things off as FindMarkers allows ident.1/2 to be either an "identity" or a vector of cell names. If you have cell names that are the same as an identity class (e.g. a cell called "1"), then the set of cells that will be used for ident.1 will just be the cell "1" instead of all cells belonging to class 1.
