(a) Microbial natural products can be detected as positive correlations between the occurrences of the microbial species and the molecules in the association network. (b) Microbial biotransformation products can be detected as negative correlations between the microbial species and the precursor molecules, along with positive correlations between the microbial species and the product molecules. The feature tables are mock-up data.
