 Raw paired-end reads are merged using SEQPREP v1.3.2 from bioconda (St. John, 2016).  This step looks for a minimum Phred quality score of 20 in the overlap region, requires at least 25bp overlap.
 
-Primers are trimmed in two steps using CUTADAPT v2.4 from bioconda (Martin, 2011).  This step looks for a minimum Phred quality score of at least 20 at the ends, forward primer is trimmed first, no more than 3 N's allowed, trimmed reads need to be at least 150 bp, untrimmed reads are discarded.  The output from the first step, is used as in put for the second step.  This step looks for a minimum Phred quality score of at least 20 at the ends, the reverse primer is trimmed, no more than 3 N's allowed, trimmed reads need to be at least 150 bp, untrimmed reads are discarded.
