# BioNetGen Features

- Modeling biochemical systems such as metabolic networks, cell-signaling pathways, and regulatory networks can be done methodically within a logical framework.
- The RuleBuilder interface provides the capability to construct a complete graphical set of reaction rules.
- An unlimited number of species and reactions can be specified as network starting seeds.
- Reaction rules allow specification of how the molecular context of individual components affects reaction rates.
- The BioNetGen Engine generates a complete network of chemical species and interactions using initial starting seeds.
- Multistate species are allowed.
- Input files can be easily modified for new uses through either the RuleBuilder interface, or by direct edit.
- Built-in support for time course simulation with standard ODE solvers.
- Results of network building and simulation are easily exportable to common analysis package formats.
