True and estimated flux values are compared for a subset of reactions of the E. coli central carbon metabolism network.

The difference is calculated between the true and estimated fluxes. Clearly, eiFlux accurately estimates the fluxes from a simulated set of measurements perturbed by simulated measurement error.
