    library(drosophila2probe)
    probes <- DNAStringSet(drosophila2probe)

    ## Check metadata slot: empty
    metadata(probes)

    ## Get generated seqinfo table
    seqinfo(probes)

    ## Subsetting seqinfo table to 10 seqnames
    probes10 <- probes[1:10]
    seqinfo(probes10) <- seqinfo(probes)[as.character(1:10)]
    ## See result: 10 seqnames
    seqinfo(probes10)
