Figure 7. Example patterns with a) two or b) three stability conditions each.

Figure 7

For each enzyme-metabolite pair, a threshold for the saturation Inline graphic is given. Enzymes are marked in red, their reactants are marked in green. Pattern 1 exhibited an average Laplace ratio of Inline graphic (Inline graphic, Inline graphic). Pattern 2 affected less training samples because of its less strict threshold on the parameter associated with PGK and GAPDH but also produced more training errors and a lower Laplace value (Inline graphic Inline graphic, Inline graphic). Pattern 3 affected an even larger number of hits but nevertheless, it produced fewer training errors than pattern 2. As a consequence, it exhibited the highest Laplace value of all the depicted patterns (Inline graphic, Inline graphic, Inline graphic).
