Finds all exchange reactions within a (community) model and report them in a data frame.
Usage
findExchReact(model)
# S4 method for class 'ModelOrg'
findExchReact(model)
# S4 method for class 'ModelComm'
findExchReact(model)Value
If 'model' is of class ModelOrg, a data.frame is returned stating all exchange reaction IDs, their index in the reaction list, the respective metabolite id, name, and index in the metabolite list. If the model is of class ModelComm, the resulting data.frame contains the community exchange reactions and the organism-specific exchange reaction. The latter are exchange reactions, that connect extracellular metabolites of the organism metabolic network models with the shared extracellular space.
Details
In cobrar, an exchange reaction is an unbalanced reaction involving a single metabolite that appears exclusively on one side of the reaction equation (either as a substrate or as a product, but not both). This structure represents the import or export of that metabolite between the system and its environment.
