Web2 Answers. Sorted by: 1. If you are going to use idents like that, make sure that you have told the software what your default ident category is. This works for me, with the metadata column being called "group", and "endo" being one possible group there. Idents (combined.all) <- "group" endo_subset <- subset (combined.all, idents = c ("endo"))

WebMar 6, 2024 · Hi, Are your cell names numbers? 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.
