Evaluation of taxonomic precision of RDP Classifier for the moderately abundant genera by referring to Best-Hit and the lowest common ancestor methods.

aTwenty-five genera accounted over 0.1% average abundance determined by all three methods were listed.bIndex of potential overestimation is the percentage of tags that were exclusively classified by RDP classifier to total classified tags for certain genus. The confidence threshold for RDP classifier is 80%. The boldface number stressed those seriously underestimated or overestimated regions with index over 50%.cIndex of potential underestimation is the percentage of tags that were exclusively classified by BH and/or LCA to total classified tags.
