I'm getting an error message while trying to perform a DEXSeq analysis. The libraries and commands I entered worked correctly a couple of years ago on an earlier R/Bioconductor build. The current R and Bioconductor packages were freshly installed a few days ago. The data consists of a set of indexed bam files and a descriptor text file containing two columns: Name and Type. The data are analysed without a problem by DESeq2.

The commands leading to the error code:

> library("Rsamtools")
> library(TxDb.Mmusculus.UCSC.mm10.knownGene)
> library(org.Mm.eg.db)
> library("GenomicAlignments")
> library("DEXSeq")
> library("annotate")
> sampleTable <- read.table("bamlist_WT-Dutch.txt", header=T, sep="\t")
> bamlist <- file.path(sampleTable$Name)
> bamfiles <- BamFileList(bamlist, yieldSize=2000000)
> sampleTableCsv <- read.csv("bamlist_WT-Dutch.txt", header=T, sep="\t")
> exonicParts <- disjointExons(TxDb.Mmusculus.UCSC.mm10.knownGene)
> exonCounts <- summarizeOverlaps(exonicParts, reads=bamfiles, mode="Union", singleEnd=F, ignore.strand=T, inter.feature=F)
> colData(exonCounts) <- DataFrame(sampleTableCsv)
> exonCounts$Type <- relevel(exonCounts$Type, "WT")
> dxdDataSet <- DEXSeqDataSetFromSE(exonCounts, design= ~Name + exon + Type:exon)
