I've downloaded a BAM file from UCSC and trying to familiarise with a few packages found in R.
I'm currently using "Rsamtools" to import the BAM file, however, I get the following error message:
Error in seqlevels(seqinfo(x)) :
error in evaluating the argument 'x' in selecting a method for function 'seqlevels': Error in .normargSeqlevels(seqnames) :
supplied 'seqlevels' cannot contain duplicated sequence names
Any idea on how to circumvent this problem?
