Statistics of cleaned reads after quality control process through Trimmomatic. In all plots, colors represent different sequencing batches. (a) Proportion of reads that passed the filtering process among all raw reads. (b) Ratio of only forward reads among paired-end reads passing the filtering process. (c) Ratio of only reverse reads among paired-end reads passing the filtering process. (d) Number of clean reads that passed the filtering process across the entire samples.
