Hi all,
I am trying to use htSeqTools to analyse some ChIP-seq samples and I
am
getting errors on the methods cmds and giniCoverage. Below I paste the
output of a session.
Any help will be greatly appreciated.
> what=c("rname", "strand", "pos", "qwidth")
> param=ScanBamParam(what = what)
>
> Con_input<-scanBam('Con_input.fastq.bam', param=param)[[1]]
>
Con_input.reads<-GRanges(seqnames=Rle(Con_input$rname),ranges=IRanges(
Con_input$pos,
width=Con_input$qwidth))
> samples<-RangedDataList(Con_input=as(Con_input.reads,"RangedData"))
> cmds1<-cmds(samples,k=2)
