COPASI is a software application for simulation and analysis of biochemical networks and their dynamics.
COPASI is a stand-alone program that supports models in the SBML standard and can simulate their behavior using ODEs, SDEs, or Gillespie's stochastic simulation algorithm. Arbitrary discrete events can be included in such simulations. COPASI provides a set analysis methods and parameter estimation, a list of all features can be found here.
The COPASI team is happy to announce a new tool, called sbmodelr, which is intended to construct large models that are composed of repeating units. Essentially, you start with a base model and then tell sbmodelr to create a number of repeat units of that model, as well as which model entities interact between units.
sbmodelr is a python-based command line utility that reads a systems biology model, encoded in COPASI or SBML formats, to create a new model that is composed of several connected units that are replicates of the base model. These units may be organized as an arbitrarily connected network, a 2D rectangular grid, or a 3D cuboid array. Each unit contains a complete copy of the original model with all its species, reactions, compartments, events, and global quantities.
