From: POSMM: an efficient alignment-free metagenomic profiler that complements alignment-based profiling
Genus-level performance scores, namely, sensitivity (SN), precision (PR), and F1-score, averaged over three simulated metagenomes (Hiseq, Miseq, and simBA-5) for Kaiju, KrakenUniq, POSMM, Kraken2, and a hybrid of Kraken2 and POSMM. Kraken2 was assessed without a confidence threshold applied. A score cutoff of 0.25 was used for POSMM. For the hybrid of Kraken2 and POSMM, initial classification was obtained with Kraken2 without a cutoff, followed by genus level classification of reads left unclassified by Kraken 2 with POSMM at 0.25 cutoff
