Hi, I am trying to run bamQC function of ATACseqQC. I am running the following command but getting an error after waiting an hour. Can somebody please advise how to handle it?

 **Code**:   bamQC("Aligned_S2.bam", index="Aligned_S2.bam.bai", mitochondria = "chrM", doubleCheckDup = FALSE, outPath = sub(".bam", ".clean.bam", basename(Aligned_S2)))

**Error:**
Error in h(simpleError(msg, call)) :
 error in evaluating the argument 'path' in selecting a method for function 'basename': object 'Aligned_S2' not found
Calls: bamQC ... sub -> is.factor -> basename -> .handleSimpleError -> h
Execution halted
