addDoubletScores fails with ‘getNTrees’ is not a valid field or method name for reference class “Rcpp_AnnoyEuclidean”>

I get the following error upon trying to compute doublet scores:

>     doubScores <- addDoubletScores(
+         input = ArrowFiles,
+         k = 10, #Refers to how many cells near a "pseudo-doublet" to count.
+         knnMethod = "UMAP", #Refers to the embedding to use for nearest neighbor search with doublet projection.
+         LSIMethod = 1
+     )

Any idea of what might cause this? Thanks

Have you run through the full tutorial with the tutorial data? This is not a normal error that we see and my assumption is that something is not set up properly on your system.

This maybe related to the R 4.0 issues? Can you attach the log file?

Could also be an error caused by the newer uwot / RcppAnnoy versions

I think this is now fixed with the new UWOT functionality, I am closing this see https://github.com/GreenleafLab/ArchR/issues/424
