Can't find a gene in single cell
Hi Biostars,
I have single-cell data with wild type and knock-out gene A. When I open the loupe file of both wild type and knock-out, I can find gene A in both samples. However, when I use Findallmarker() on the Seurat object from wild type, I don't find gene A, even after setting logfc.threshold = 0 and minpct = 0.1. This made me very confused. Gene A should show in the wild type sample. Would you please have a suggestion? Sorry but I don't know anyone else to ask.

Your gene is probably not differentially expressed in any identity group of your dataset
Got it. Thank you so much. I will try with
FindConservedMarkers(). Would you please have a suggestion to find gene A?FeaturePlotof gene A is not clear. Seem expression level of this gene is quite low.What do you mean by "find gene A" ? If it is lowly expressed, it is likely that it would not be a marker of any of your cells identity groups. You cannot force an analysis to make a gene as differentially expressed.
I mean to find which clusters that gene express and the cell type of those clusters.
