Bug Fixes

  • Graphical User Interface (CopasiUI)
    • Fixed issue where loading a parameter estimation protocol in which the values had been sorted externally lead to incorrect parameter mapping.
    • Show both modification and creation time entities in local time.
    • Fixed plot for parameter estimation results for steady state experiments to properly map the independent data.
    • The parameter estimation result now includes a counter for failed constraints.
    • Fixed crash when deleting all global quantities.
  • Simulation Engine
    • Fixed temporary directory for export of Combine and Shiny archives to address security restrictions on MacOS X.
    • Stochastic simulation methods now correctly report whether they support events and thus whether they can be used for the simulation of model with events.
  • Standards
    • SBML import: Fixed issue where it was not possible to change the delay of an imported event.
    • SBML import: Fixed crash caused by particular unit definitions during importing.
    • SBML import: Fixed import of reaction kinetics which occasionally lost the parameter mapping.
    • SBML import: Handle references to missing modifier species in reactions gracefully.
    • SBML export: Reduced warnings about Model History not being exported to only check the model itself and not all model components.
