Comparison of models extracted by the four evaluated contending methods: Mean values across contexts.

Global characteristics of the models are derived by applying RegrEx (with automated determination of λ), RegrEx-λ0 (i.e., RegrEx without regularization), Lee2012, iMAT and FastCORE. The abbreviations stand for the following:

Card.
-

denotes mean cardinality,

O
-

R, mean data-orphan ratio,

ρ
-

(V,D), mean correlation between data and predicted flux values,

R
-

(V,D), mean residual value between fluxes and data
, 

I
-

J, mean Jaccard index to any other context, Shared, number of shared reactions across all contexts, and Total Exclusive represents total number of exclusively context-specific reactions across all contexts. Values in round brackets correspond to the standard deviation.
