From: POSMM: an efficient alignment-free metagenomic profiler that complements alignment-based profiling

The number of reads assigned by POSMM at 0.25 cutoff and Kraken2 (no cut-off) to each species represented in the SRR8073716 mock metagenome. For the hybrid of Kraken2 and POSMM, initial assignment was obtained with Kraken2 without a cutoff, followed by genus level assignment of reads left unassigned by Kraken 2 with POSMM at 0.25 cutoff. “Direct” refers to read assignment using genome-specified bwa alignments in the original study
