The structure of these files is straightforward: the first line contains column names (in no specific order) that define the data represented in each column, followed by lines that provide the data for individual compounds or reactions. To enhance user flexibility, column names are categorized as either "required" or "optional". The "required" columns constitute the essential data needed to define a compound or a reaction. For instance, the "compounds" file mandates the name and energy columns, whereas the "reactions" file requires at least one cleft and one cright column. During the parsing process, rNets checks for the presence of these required columns in the input files. Conversely, the "optional" columns allow for additional, user-specific customizations to each compound or reaction. This flexibility enables users to tailor the analysis to their specific needs. Tables Tables summarize this information, offering users a quick reference guide for efficient data organization and input into rNets, also included in the code repository.
