Abstract

The set of extreme pathways, a generating set for all possible steady-state flux maps in a biochemical reaction network, can be computed from the stoichiometric matrix, an incidence-like matrix reflecting the network topology. Here, we describe the implementation of a well-known algorithm to compute these pathways and give a summary of the features of the available software.

AVAILABILITY:

The C-code, along with a Windows executable and sample network reaction files, are available at http://systemsbiology.ucsd.edu
