Compounds in LANaPD were classified with NPClassifier which is a freely available deep neural networkbased structural classification tool for NPs. NPClassifier establishes a classification system based on the literature from the specialized metabolism of plants, marine organisms, fungi, and microorganisms. The categories used in NPClassifier are defined at three hierarchical levels: Pathway (nature of the biosynthetic pathway), Superclass (chemical properties or chemotaxonomic information), and Class (structural details).
