Question

[zhao03]

Hi, three kind of clusters i discoverd by different dim, now i want to use result of res.0.4 to plot UMAP.

However, there is error when i used the command as fllowing:

Idents(D3_APLNR)<-"res.0.4"
Error in UseMethod(generic = "Idents<-", object = object) : no applicable method for 'Idents<-' applied to an object of class "seurat"

how can i select res.0.4 to plot? thank you!

..@ meta.data   :'data.frame':        8591 obs. of  13 variables:
  ..$ nGene       : int [1:8591] 2135 2049 2429 2775 2079 2661 2572 2810 2292 3391 ...

Hello, if you have your results in different assays I think you need to set the default assay to the one you want to display

DefaultAssay(object = D3_APLNR) <- "res.0.4"
RunUMAP(object = D3_APLNR)

Try:

Idents(D3_APLNR)=D3_APLNR$res.0.3
