Taxonomic classification using core bacterial HMMs with phylogeny inferred based on placement on the reference tree of core bacterial HMMs from all sequenced bacterial genomes. Taxonomic groups of interest are highlighted as follows: blue = Proteobacteria, red = Firmicutes, light blue = Actinobacteria, green = Cyanobacteria, white = Planctomycetes, yellow = Bacteroidetes. Heatmaps were generated based on the abundance of taxonomy at each node within the reference tree for every group of samples.
