From: PFA toolbox: a MATLAB tool for Metabolic Flux Analysis
PFA Toolbox methodology to solve example of flux estimation under data scarcity. a Upper panel present a simple metabolic network. Metabolites are in capital letters, each vj represent a flux and the double arrows indicate a reversible reaction. b The step-by-step procedure follow to solve the MFA problem where only two measures are known. c Right panel shows the MATLAB code used to perform the computations
