From: SILVA, RDP, Greengenes, NCBI and OTT — how do these taxonomies compare?
Comparison of taxonomies based on taxon names found at each rank from phylum to genus. The four taxonomies, SILVA, RDP, Greengenes and NCBI, commonly used for metagenomic analyses are compared in detail (Venn diagrams on the left) and then union of them (labeled ALL) is compared against OTT (Venn diagrams on the right). Colour intensity corresponds to the percentage of taxonomic units in the intersection. Produced with Venny 2.1 [33]
