Classifies metagenomic sequence data using unique k-mer counts
Input
name:type
description
pattern
meta:map
Groovy Map containing sample information
e.g. [ id:‘test’, single_end
]
sequences:file
List of input files containing sequences. All of them must be either in FASTA or FASTQ format.
prefixes:string
List of sample identifiers or filename prefixes. Must correspond in order and length to the ‘sequences’, or to the number of sequencing pairs.
sequence_type:string
Format of all given sequencing files as literal string, either ‘fasta’ or ‘fastq’.
{fasta,fastq}
db:directory
KrakenUniq database
ram_chunk_size:string
Amount of maximum amount of RAM each chunk of database that should be loaded at any one time
*GB
save_output_reads:boolean
Optionally, commands are added to save classified and unclassified reads
as FASTQ or FASTA files depending on the input format. When the input
is paired-end, the single output FASTQ contains merged reads.
report_file:boolean
Whether to generate a report of relative abundances.
save_output:boolean
Whether to save a file reporting the taxonomic classification of each input read.
