Introduction

Another tool for quality trimming ... this is probably the best known.

Usage

Trimmomatic is quite unique in the way it is called.

It is a java program, so this requires the jar file naturally, and then:

  1. whether single- or pair-end reads (SE|PE)
  2. number of threads with hyphen, i.e. -threads N
  3. whether quality scoring is phred33 or phred64 (although it will try to detect)

  • $NXPE is NexteraPE-PE.fa
  • $TS3PE is TruSeq3-PE.fa
  • $TS3PE2 is TruSeq3-PE-2.fa
