Summary of the performance of MotifCluster using motifs found by MEME and the Gibbs sampler for 741 pairs of families in the gold-standard set of families. (a) Incorrect inferences of superfamily assignment. (b) Failure to assign sequences to the leading component (for members of the same superfamily) or to one of the two leading components (for members of two different superfamilies). The numbers 1 and 2 in the legend (for example, Gibbs 1 and Gibbs 2) refer to the two largest components, which invariably contain most of the sequences from the two distinct families when these families belong to different superfamilies.
