abstract = {MotivationThe validity of model based inference, as used in
systems biology, depends on the underlying model
formulation. Often, a vast number of competing models is
available, that are built on different assumptions, all
consistent with the existing knowledge about the studied
biological phenomenon. As a remedy for this, Bayesian Model
Averaging (BMA) facilitates parameter and structural
inferences based on multiple models simultaneously. However,
in fields where a vast number of alternative,
high-dimensional and non-linear models are involved, the
BMA-based inference task is computationally very
challenging.ResultsHere we use BMA in the complex setting of
Metabolic Flux Analysis (MFA) to infer whether potentially
reversible reactions proceed uni- or bidirectionally, using
13C labeling data and metabolic networks. BMA is applied on
a large set of candidate models with differing
directionality settings, using a tailored multi-model Markov
Chain Monte Carlo (MCMC) approach. The applicability of our
algorithm is shown by inferring the in vivo probability of
reaction bidirectionalities in a realistic network setup,
thereby extending the scope of 13C MFA from parameter to
structural inference.},
