RESCRIPt: Reproducible sequence taxonomy reference database management

Taxonomic information (A-C) and classification accuracy (D-E) of Greengenes 16S rRNA gene database clustered at different similarity thresholds. Subpanels show taxonomic/classification characteristics at each taxonomic level: A, Number of unique taxonomic labels; B, Taxonomic entropy; C, number of taxa that terminate at that level; D, optimal classification accuracy (as F-Measure) without cross-validation (simulating best possible classification accuracy when the true label is known but classification accuracy may be confounded by other similar hits in the database); E, classification accuracy (F-Measure) with cross-validation (simulating realistic classification tasks when the correct label is unknown). Rank labels on x-axis: D = domain, P = phylum, C = class, O = order, F = family, G = genus, S = species.
