Assume the input is in reads.1.fastq and reads.2.fastq and that ADAPTER_FWD should be trimmed from the forward reads (first file) and ADAPTER_REV from the reverse reads (second file). The basic command-line is:

WebOct 26, 2024 · Trimming by SnapGene is performed by the same algorithm as that used when hiding chromatogram ends at medium stringency, except low quality ends are removed rather than hidden prior to passing the reads to the CAP3 assembler (see Set the Default Stringency for Hiding Chromatogram Ends). Note that the CAP3 algorithm may … WebIf LENGTH is negative, remove bases from the end. Can be used twice if LENGTHs have different signs. -q [5'CUTOFF,]3'CUTOFF, --quality-cutoff = [5 'CUTOFF,]3'CUTOFF Trim low-quality bases from 5' and/or 3' ends of each read before adapter removal. Applied to both reads if data is paired. If one value is given, only the 3' end is trimmed.
