Heatmap of the precision score S _i levels estimated by the computer simulation of ¹³C-MFA using 10 mixtures of non-labeled, [1-¹³C], [2-¹³C], and [U-¹³C]ethanol as the carbon sources. The magenta and green colors in the boxes represent narrower (better precision) and wider (poorer precision) 95% confidence interval levels of the estimated metabolic fluxes on each reaction, respectively
