Theoretical studies of reaction networks frequently rely on ab-initio methods to compute thermodynamic and kinetic properties, such as ground-state energies of compounds and activation energies of reactions. These properties are typically collated into simple, spreadsheet-like tables for easy parsing and analysis. Reaction path plots, a popular visualization method, excel in depicting these tables, especially for simple mechanisms. Recognizing the simplicity and widespread use of table formats in the research community, rNets has been tailored to interface seamlessly with input files resembling these tables. This design strategy is aimed at facilitating the adoption of rNets, especially among chemists with limited programming expertise. rNets utilizes two primary file types to define a reaction network: the "compounds" file, detailing the compounds, and the "reactions" file, outlining the reactions. The chosen file format for both is comma-separated values (CSV), balancing simplicity and versatility.
