Read classification of low-complexity in silico synthetic communities using Kraken. a The proportion of mappable reads generated from synthetic communities composed of 5, 10, or 20 S. epidermidis or B. fragilis strains. b The proportion of mapped reads versus inconsistently classified reads generated from synthetic communities composed of five different Staphylococcus or Bacteroides species, or species representing five different bacterial phyla. “Inconsistent” means the read was neither assigned to the species from which it was sampled nor assigned to the an ancestral taxon of the species from which it was sampled
