    #compute differential methylation
    pcols <- c("Sample_Group","Treatment")
    tdir <- tempfile(pattern="working")
    dm <- rnb.execute.computeDiffMeth(rnb.set.example,pcols,disk.dump=TRUE,disk.dump.dir=tdir)
    #get temporary file names
    fn.save.tabs <- tempfile(pattern="saveTables")
    fn.save.obj  <- tempfile(pattern="saveObject")
