Hello, I have metabolic reactions in data frame format. Key variables are WholeCellModelID (reaction ID), Enzyme (enzyme ID), Stoichiometry (reaction description in the format like [c]: COA + NAD + PYR <==> ACCOA + CO2 + NADH). So, it is easy to reshape this data if necessary. The question is What are basic steps and packages required to visualize these data as metabolic network?
