kraken2Kraken 2 is a taxonomic sequence classifier for assigning taxonomic labels to DNA sequences. It leverages a highly efficient minimizer-based k-mer mapping algorithm allowing fast, low-memory classification of metagenomic reads against large reference databases.Versions

v2.17.1 (default)

Tags: bioinformatics, taxonomic classification, metagenomicsParameters

database (enum) required: Kraken2 database to use for classification. Options: k2_pluspf_16_GB_20260626, babykraken

input_files (file, multiple): FASTA or FASTQ format input files (supports paired-end if --paired set).

paired (bool): Treat input files as paired-end reads.
