COPASI (COmplex PAthway SImulator) is an open-source software application for creating and solving mathematical models of biological processes such as metabolic networks, cell-signaling pathways, regulatory networks, infectious diseases, and many others.

Features

COPASI includes features to define models of biological processes, simulate and analyze these models, generate analysis reports, and import/export models in SBML format. * Model definition: Models are defined as

chemical reactions A chemical reaction is a process that leads to the IUPAC nomenclature for organic transformations, chemical transformation of one set of chemical substances to another. Classically, chemical reactions encompass changes that only involve the pos ...

between molecular species. The dynamics of the model is determined by

Rate law In chemistry, the rate law or rate equation for a reaction is an equation that links the initial or forward reaction rate with the concentrations or pressures of the reactants and constant parameters (normally rate coefficients and partial reac ...

associated with individual reactions. Models can also include compartments, events, and other global variables that can help specify the dynamics of the system. * Tasks: Tasks are different types of analysis that can be performed on a model. They include steady-state analysis, stoichiometric analysis, time course simulation using deterministic and stochastic simulation algorithms,

metabolic control analysis Metabolic control analysis (MCA) is a mathematical framework for describing metabolic, signaling, and genetic pathways. MCA quantifies how variables,elastsuch as fluxes and species concentrations, depend on network parameters. In particular, it i ...
