Heatmap indicating the sum of genome copies per million reads per class for each bacterial class represented by the SRGs per sample. White indicates that reads from the given class were not detected in the sample. In the figure, the color yellow/khaki starts at 0.0001 genome copies per million reads. The heatmap is hierarchically clustered.
