I am trying to use cn.mops for Whole Exome Sequencing with paired-reads through running the following code:

res_calCNMOPS <- calcIntegerCopyNumbers(resCNMOPS)

and get error message like this,

Error in `[[<-`(`*tmp*`, name, value = c("CN0", "CN0", "CN0", "CN0", "CN0",  :
  367 elements in value to replace 365 elements

The complete code I used is here:

> library(cn.mops)
> BAMFiles <- c("tumor_hg19.sorted.bam","normal_hg19.sorted.bam")
> BAIFiles <- c("tumor_hg19.sorted.bam.bai","normal_hg19.sorted.bam.bai")
> segments <- read.delim("~/hg19.bed",sep="\t",header=FALSE,as.is=TRUE)
> gr <- GRanges(segments[,1],IRanges(segments[,2],segments[,3]))

> X <- getSegmentReadCountsFromBAM(BAMFiles,GR=gr,mode="paired")

This may take a couple of minutes per BAM file.Please be patient.

The R, cn.mops and Rsamtools packages had been upgraded to the latest version. I tried many tumor and normal paired files and got the similar error message.

Could any one please help me with this?
