Failing to plot UMAP after integration

[VDD58]

Hi,
I have 10x scATAC data that i am analyzing using ArchR.
Currently I am trying to perform an unconstrained integration of scRNA data (SMART-seq) but unfortunately I am unable to plot an UMAP after integration. I receive the following error:

Error in getEmbedding(ArchRProj, embedding = embedding, returnDF = TRUE): Embedding not in computed embeddings, Current ones are : UMAPHarmony_res_0.3,UMAP_res_0.3
Traceback:

1. plotEmbedding(proj2.1_integrated, colorBy = "cellColData", name = "predictedGroup_TTT",
   . pal = pal)
2. getEmbedding(ArchRProj, embedding = embedding, returnDF = TRUE)
3. stop(paste0("Embedding not in computed embeddings, Current ones are : ",
   . paste0(names(ArchRProj@embeddings), collapse = ",")))

I really do not understand why this is happening considering that both embeddings are present in the ArchR project.
proj2.1_integrated@embeddings
List of length 2
names(2): UMAPHarmony_res_0.3 UMAP_res_0.3

If you have any suggestions, they will be highly appreciated.

The default value for the embedding parameter is "UMAP". From what I can tell, you havent provided a value for that parameter so it has defaulted to the name "UMAP" which isnt available in your project.

Thank you!
I have included embedding = "UMAP_res_0.3" and of course it worked!
Thank you again!
