Mapping abundance levels of reads to OTUs. The proportions of reads mapping to genera, for each week, grouped into clusters that represented distinct sets of genera. Read counts were first converted to percent proportions before undertaking cluster analysis. Hierarchical clustering using Euclidean distances of read abundance levels was used to construct the heatmap. The adult mice formed the largest cluster with maximum number of reads mapping to unique OTUs. The genera with maximum abundance per week out of the 269 genera has been given below
