Before revision:  MetaboX includes methods to extract information about a resource of interest (e.g. metabolite, reaction and enzyme) for further processing and storing purposes. MetaboX is modular, thus developers can contribute with alternative implementations or extensions. Each component of the library is designed with minimum dependency on other components. Supplementary information available in Table 1. Availability The MetaboX library is available under the AGPL license on gitHub repository URL
After revision:  MetaboX includes methods to extract information about a resource of interest (e.g. metabolite, reaction and enzyme) and to build reactants networks, bipartite enzyme-metabolite and unipartite enzyme networks. These networks can be exported in different formats for data visualization with standard tools. As a case study, the networks built from a subset of the Glycolysis pathway are described and discussed. Conclusions: The advantages of using such a library imply the ability to model complex systems with few starting information represented by a collection of metabolites KEGG IDs.
