title: Genetic Network Analyzer: qualitative simulation of genetic regulatory networks.
abstract: BACKGROUND
  The study of genetic regulatory networks has received a major impetus from the recent development of experimental techniques allowing the measurement of patterns of gene expression in a massively parallel way. This experimental progress calls for the development of appropriate computer tools for the modeling and simulation of gene regulation processes.
  
  
  RESULTS
  We present Genetic Network Analyzer (GNA), a computer tool for the modeling and simulation of genetic regulatory networks. The tool is based on a qualitative simulation method that employs coarse-grained models of regulatory networks. The use of GNA is illustrated by a case study of the network of genes and interactions regulating the initiation of sporulation in Bacillus subtilis.
  
  
  BACKGROUND
  GNA and the model of the sporulation network are available at http://www-helix.inrialpes.fr/gna.
