The first column indicates the number of reactions that belong to a RS. The second and third columns indicate how many RS with a given number of reaction are in model iMP240 and iCG238, respectively. The fourth column shows how many RS pairs are equal in both models and for a given number of reactions. In the last columns, the number out of the parenthesis indicate how many RS with a Jaccard index greater than 0.75 have been found, taking as the reference point the model iMP240. The number in parenthesis indicates the difference of reactions between a pair of RS in the following way: a positive number means that the RS in iCG238 has this number of additional reactions whereas a negative indicate the opposite.
