Statistical graphs provided in an HTML report. (a). Overview of the range of quality values across all bases at each position in a FASTQ file. (b). Proportion of each base at each position in the FASTQ files before and after quality control. (c). Percentages of reads filtered by different criterion. ‘+’ indicates reads that were filtered by more than one criterion. (d). Number of reads containing adapter sequence at different overlapping bases. (e). Percentages of each base in the FASTQ files. (f). Length distribution of sequences
