Biologically similar results automatically produced by WATERS on published colonic microbiota samples. (A) Rarefaction curves similar to curves shown in Eckburg et al. Fig. 2; 70-72, indicate patient numbers, i.e., 3 different individuals. (B) Weighted Unifrac analysis based on phylogenetic tree and OTU data produced by WATERS very similar to Eckburg et al. Fig. 3B. (C) Neighbor-joining phylogenetic tree (Quicktree) representing the sequences analyzed by WATERS, which is clearly similar to Fig. S1 in Eckburg et al.
