            Here we show aggregated quality statistics for every sequencing library. It shows the total number of reads used after quality control, and the total number of reads discarded during quality control. This is done for both forward and reverse reads.
            We show two plots; one for the forward read in the pair, and another one of the reverse read in the pair.
            Red denotes number of reads left after QC. Green denotes reads filtered by adaptor clipping.
            Blue denotes number of reads filtered by read trimming.
            Purple denotes the amount of <em>synced</em> reads. That is, reads removed in one orientation should be removed in the other as well to ensure correctness.
