`fastq` | Fastq to demultiplex containing mate 1s. Different pairs should be named as "_R1" or "_R2". Allowed formats: _R1.fastq.gz, _R1.fq.gz, _R1.fastq or _R1.fq.

    barcodes <- data.frame(
        sample = c("CIITA"),
        barcode = c("GGACAAGCTCCCTGCAACTCA")
    )

    demultiplexFastq(
        barcodes = barcodes,
