Principal component analysis of the model’s fluxes. Graphical representation of strain fluxes projected on the two plans defined by the three first axes of the PCA calculated from 14 predicted fluxes for 43 strains. The strains are represented as dots colored by the function of strain origin. On top of each graph is the circle of variables. The red lines correspond to constrained fluxes and the blue lines to predicted fluxes. Plan defined by axis 1 and 2 of the PCA (a). Plan defined by axis 2 and 3 of the PCA (b)
