I was recently given a data set (run through Illumina in 2014) to merge with a set run through Illumina this year. The set I just received was not demultiplexed and was dual barcoded. I know that Illumina's bcl2fastq can handle dual barcoded sets and demultiplex, but I don't have any of the BaseCall data it typically uses to demultiplex. I only have .fastq.gz files and a mapping file to work with. Does anyone know if I can still use the bcl2fastq without the BaseCall data, or if there is something that would work better?
tldr; I need to demultiplex dual barcoded .fastq.gz files
