COPASI 4.41 (Build 283)

Version 4.41.283

Release Date: November 21, 2023

New Features since COPASI 4.40 (Build 278)

• Simulation Engine
  • Species particle numbers are no supported as event targets.
  • Optimization & Parameter Estimation: It is now possible to run current solution statistics before adding any optimization parameters.

Bug Fixes since COPASI 4.40 (Build 278)

• Graphical User Interface (CopasiUI)
  • Reduced COPASI's start up time.
  • Fixed display of message boxes under Qt 6.5.
  • Improved functionality and stability of the plotting engines QWT & QCustomPlot
  • The output assistant suppresses now any check boxes which are not applicable to the current task.
  • Improved display of SBML imported units.
  • Fixed rare crash occurring when lading a new file while displaying a global quantity.

Simulation Engine

• Utilize balanced Abstract Syntax Tree to avoid stack overflows.
• Fixed loading of COPASI files containing parameter estimation created with COPASI 4.0 (Build 18).
• The COPASI Version is now correctly displayed in reports.
• Fixed an error message for trajectory method RK45 which was referring to LSODA.

Standards

• SBML Import: Corrected function parameter classification which effected the UI parameter overview.
• SBML Import: Avoid redundant division by log(10) when importing logarithm with base 10.
• SBML Import (layout): Allow import of empty curves.
• SED-ML Import: Improved import of SED-ML files with multiple task lists, falling back to SBML when all fail.
• SED-ML Import: Create a warning message when referenced the SBML model is remote resource (unsupported).

API & Language Bindings

• Added utility function CFunctionDB::purgeUnusedUserDefinedFunctions().
• Added editing of constraints in optimization and parameter estimation tasks.
