MetMAP is a MATLAB Toolbox for Metabolical Modeling, Analysis and oPtimization (Met. M. A. P.). You can use this package to study metabolical systems from a theoretical point of view, analysing the pathway s structure and dynamics, but you can also use it for biotechnological purposes, evaluating optimal solutions in a genetical improvement process. All this calculations are evaluated using the S-System formalism (a part of Biochemical Systems Theory, BST) and the Indirect Optimization Method (IOM, developed by Torres, Voit et al).
