Error : object 'anno.mat' not found

Hi copyKAT team,

I wanted to run copyKAT on a single-cell data but I encountered an error:

> copykat.test <- copykat(rawmat=copyKAT.input, 
+                         id.type="S", 
+                         ngene.chr=5, 
+                         win.size=25, 
+                         KS.cut=0.1, 
+                         sam.name="test", 
+                         distance="euclidean", 
+                         norm.cell.names="",
+                         output.seg="FLASE", 
+                         plot.genes="TRUE", 
+                         genome="hg38",
+                         n.cores=4)

Error in copykat(rawmat = copyKAT.input, id.type = "S", ngene.chr = 5, :
object 'anno.mat' not found

I prepared my input matrix from my Seurat object by extracting the raw counts table.
copyKAT.input <- seuratobject@assays$RNA$counts

cellranger uses both Gene symbols and Ensembl identifiers for the genes, so I removed those genes that have Ensembl IDs:
copyKAT.input <- copyKAT.input[!grepl("^ENSG", rownames(copyKAT.input)), ]
However, I still got the same error.

The single cell data is from human and was made by cellranger-9.0.1 and GRCh38-2024-A.
Could you please suggest a solution for this error?
Many thanks for your help in advance.

Apparently the process does not generate an error and proceed forward when i use : genome="hg20". In the github description it was mentioned that hg38 was added, and i misunderstood whether we need to add hg20 or hg38. So I guess problem solved :)
