Fig. 4

The differences of the gut microbiotas between babies born vaginally and those by C-section. A phylogenetic tree of 464 metaOTUs is shown in the innermost circle. MetaOTU abundance collected from newborns at three time points: 4 days (0M), 4 months (4M), and 12 months (12M), is shown in the heatmap with log-abundance normalized to [0,1] over samples. To avoid displaying all (285) samples, average samples that are generated by randomly assigning samples within a group into 5 categories and averaging counts of each metaOTU within each category are used. Branches detected to be DA at 0M, 4M, and 12M are shown in the circular black bars between the heatmap and the tree. On the tree, orange branches are those detected to be different at least in one time point. Red dots show nodes found by treeclimbR for newborns (0M). Genera that have at least 5 metaOTUs reported are shown
