New Features in this Release compared with last stable Release

  • Graphical User Interface (CopasiUI)
    • Sorting and filtering in tables, which eases handling of large models.
    • Enhanced result representation of elementary flux mode analysis.
    • Improved SBW registration to handle multiple COPASI installations.
  • Simulation Engine
    • Support of conditional events, which are discrete changes to the model.
    • 2 new stochastic simulation algorithms, which implements the direct Gillespie algorithm and Tau-Leap method.
    • Eigenvalues of the steady-state Jacobians are now available for further processing or output.
