Figure 5. Compound-pairs share superclass annotation at a greater frequency as substructure similarity scores increase.

Ratio of compound-pairs substructure similarity with matched and unmatched superclass annotation for all compound pairs represented in MicrobeFDT. Within the hierarchical ClassyFire classification schema, the superclass level annotation represents the second level and includes 31 different structure-based categories (Djoumbou Feunang et al., 2016).
