Perform adapter/quality trimming on sequencing reads
Input
name:type
description
pattern
meta:map
Groovy Map containing sample information. Use ‘single_end: true’ to specify single ended or interleaved FASTQs. Use ‘single_end: false’ for paired-end reads.
e.g. [ id:‘test’, single_end:false ]
reads:file
List of input FastQ files of size 1 and 2 for single-end and paired-end data,
respectively. If you wish to run interleaved paired-end data, supply as single-end data
but with --interleaved_in in your modules.conf’s ext.args for the module.
adapter_fasta:file
File in FASTA format containing possible adapters to remove.
*.{fasta,fna,fas,fa}
discard_trimmed_pass:boolean
Specify true to not write any reads that pass trimming thresholds. | This can be used to use fastp for the output report only.
save_trimmed_fail:boolean
Specify true to save files that failed to pass trimming thresholds ending in \*.fail.fastq.gz
save_merged:boolean
Specify true to save all merged reads to a file ending in \*.merged.fastq.gz

Tools
fastp
MIT
A tool designed to provide fast all-in-one preprocessing for FastQ files. This tool is developed in C++ with multithreading supported to afford high performance.
