Classification accuracy for each taxon at different ranks of the NCBI taxonomy. Classification accuracy for each taxon at different ranks of the NCBI taxonomy. For better visualization of names for the internal nodes, the taxon names are displayed on branches leading to the respective taxon node in the tree. The nested cross-validation accuracy obtained with Traitar for 234 bacterial species described in GIDEON was projected onto the NCBI taxonomy down to the family level. Colored circles at the tree nodes depict the performance of the phypat+PGL classifier (left-hand circles) and the phypat classifier (right-hand circles). The size of the circles reflects the number of species per taxon. Aaron Weimann et al. mSystems 2016; doi:10.1128/mSystems.00101-16
