Estimated metabolic fluxes values for the different approaches - the ad-hoc simulation results from Becker et al. [18], the OpenFLUX results [15], and the FIA results for its various simulated scenarios (measured fluxes used as constants, as measurements, and when using ratios of non-normalized data.)
