Fig. 3From: Improved taxonomic assignment of human intestinal 16S rRNA sequences by a dedicated reference databaseTaxonomic assignment accuracy. Proportions of correctly assigned synthetic reads relative to the total number of assignments (left) and relative to assigned sequences only (right). The 16S sequence regions V1-V3 and V4-V6 are shown separately at genus and species levels in Greengenes and HITdb. The box plots represent variation over 1000 bootstrapsBack to article page
