Heatmap of the correlation between bacterial and metabolites.
Correlations network of fungi, bacteria, and metabolites.

The orange module represents metabolites. The yellow module represents bacteria. The green module represents fungi. The red line represents positive correlations. Blue line represents negative correlations. The thickness of the lines represents the magnitude of the correlation coefficient.
