Genetic Network Analyzer 8.0Free
Allows the user to model and simulate genetic regulatory networks.
GNA (Genetic Network Analyzer) is a computer tool for the qualitative modeling and simulation of genetic regulatory networks. GNA assists you in constructing a model of a genetic regulatory network using knowledge about regulatory interactions in combination with gene expression data. Moreover, it allows you to simulate the qualitative behavior of the network in response to external perturbations. The mathematical models created with GNA can be tested against observed properties of the network.
