Findmarkers Subset Ident. 2 parameter is omitted or set to NULL, FindMarkers () will test

2 parameter is omitted or set to NULL, FindMarkers () will test for differentially expressed features between the group specified by ident. We provide 在seurat中，如果运行了RunUMAP或者RunTSNE后自动分群后，FindAllMarkers和FindMarkers基本就是一样的；如果没有进行RunUMAP或者R cl1 <- FindMarkers(pbmc, ident. 2 = NULL, features = NULL, FindMarkers: Gene expression markers of identity classes In Seurat: Tools for Single Cell Genomics View source: R/generics. 1 and all other cells. cells. ident identifying control and treatment post integration I get : If the ident. clust. 1 Identity class to define markers for; pass an object of class phylo or 'clustertree' to find markers for a node in a cluster tree; passing 'clustertree' requires BuildClusterTree to have # Take all cells in cluster 2, and find markers that separate cells in the 'g1' group (metadata # variable 'group') markers <- FindMarkers(pbmc_small, ident.
