Enhancing Elementary Flux Modes Analysis Using Filtering Techniques in an Integrated Environment

Abstract. Elementary Flux Modes (EFMs) have been claimed as one of the most promising approaches for pathway analysis. These are a set of vectors that emerge from the stoichiometric matrix of a biochemical network through the use of convex analysis. The computation of all EFMs of a given network is an NP-hard problem and existing algorithms do not scale well. Moreover, the analysis of results is diffi-cult given the thousands or millions of possible modes generated. In this work, we propose a new plugin, running on top of the OptFlux Metabolic Engineering work-bench, whose aims are to ease the analysis of these results and explore synergies among EFM analysis, phenotype simulation and strain optimization.
