Welcome to the Lectures Wiki Metabolic Networks SS 2015


General information

SWS: 2+1, ECTS: 5

Lecturer: Alexander Bockmayr
Tutor: Therese Lorenz

Language: English / German


Lecture: Thursday 14-16h Arnimallee 6 SR 025/026
Exercise (every two weeks): Thursday 16-18h Arnimallee 6 SR 025/026


The goal of this course is to give an introduction to the most important mathematical and algorithmic ideas underlying the constraint-based analysis of genome-scale metabolic networks, with applications to systems biology and biotechnology.

We will discuss the steady-state flux cone, flux balance analysis (FBA), flux variability analysis (FVA), flux coupling analysis (FCA), elementary flux modes (EFMs), thermodynamic constraints, and metabolic regulation. On the algorithmic side, the focus will be on linear and mixed-integer optimisation methods.

Minimum requirements

Active and regular attendance at exercises


Please sign in for the mailinglist to get shortterm informations about the tutorials : https://lists.fu-berlin.de/listinfo/MetabolicNetworksSS15


Exercise sheet 1 (due 30.04.): MetabolicNetworks_Ex1.pdf. The testing examples can be downloaded here: MetabolicNetworks.zip

Exercise sheet 2 (due 14.05.): MetabolicNetworks_Ex2.pdf. The article needed for the last exercise is F2C2 Article.
Edited: In Exercise 4d the inference rules are the transitivity rules of the coupling relations.
Second chance: Due 04.06.

Exercise sheet 3 (due 18.06.): MetabolicNetworks_Ex3.pdf. The script of the tutorial: DeFig.pdf.
The small testing examples can be downloaded here: BeispielNetzwerke.zip, as more interesting examples use the examples of exercise 1.
Be careful: The small examples have individual names, instead of the standard name 'network', so your program may either accept a previously loaded struct as argument or determine the correct field name by using 'model = load('struct.mat'); names = fieldnames(model);'
Additional material : Computing the shortest elementary flux modes in genome-scale metabolic networks by Luis de Figueiredo et al.
Algorithm: shortestEFMs.m

Exercise sheet 4 : MetabolicNetworks_Ex4.pdf. For the next tutorial you should read the this Article and especially focus on your example (Ex. 1 - Marthe, Balduin; Ex. 2 - Marjan, Moritz; Ex. 3 - David, Pascal).
