Error in step 2: arguments imply differing number of rows

[carbui]

Hi,

I am running copykat on my single cell data from mouse. It runs with no problems in all the samples except this one, which should be all tumor cells and I can´t understand why. My tumor cells have been previously transduced to express mCherry. Maybe it is a problem in annotating mCherry to the normal genes of the mouse genome?

Thanks for the great package and help!

mat <- readMM("matrix.mtx.gz")
genes <- read.table("features.tsv.gz", header = FALSE, stringsAsFactors = FALSE)
barcodes <- read.table("barcodes.tsv.gz", header = FALSE, stringsAsFactors = FALSE)

gene_symbols <- genes$V2
cell_barcodes <- barcodes$V1

rownames(mat) <- gene_symbols
colnames(mat) <- cell_barcodes

copykat.1T <- copykat(rawmat=mat, id.type="S", ngene.chr=5, win.size=25, KS.cut=0.1, sam.name="1T", distance="euclidean", norm.cell.names="",output.seg="FLASE", plot.genes="FALSE", genome="mm10",n.cores=1)

there are duplicates in the gene names in the original count matrix, remove them
