WebGenerally, higher duplicated read percentage is welcome as it represents better sequencing depth and lower sequencing error contamination. This dsitribution in this plot looks reasonable and nothing unusual. fastqc … WebNov 13, 2024 · One way to deal with this would be to first merge paired-end reads based upon their overlapping regions, and then map them and calculate the coverage. This way you're only counting once per unique sequence. Programs like SeqPrep, PEAR (Paired-End reAd mergeR), and fastq-join can do this fairly quickly.
