COPASI 4.0.20 (development)

Version 4.0.20 (development)

Release Date: February 9, 2007

New Features

• New optimization methods Particle Swarm.
• New Sensitivities Task in the multiple task section.
• Intel support for MacOS X through universal binaries.

Bug Fixes

• Units are now also shown for Mass Action kinetics.
• Improved format for kinetic parameters in Madonna export.
• Fixed problem where the GUI might stop responding after overnight calculations.
• The slider dialog no longer interferes with other COPASI windows.
• Improved SBML import of rules.
• Corrected list of reactions involving the currently shown metabolite.
• Fixed problem with delayed output for time course task.
• Enhanced layout of single function display to give more space to the formula.
• Prevented hanging of COPASI in rare situations when entering the single function display.
• Fixed problems where deletion of compartments, metabolites, or reactions might COPASI to crash.
• Enhanced display and handling of weights in the experimental data dialog so that copy settings works as expected by the user.
• Fixed problem where repeated SBML export might lead to COPASI crashes.
• Start values are no working correctly for optimization. Previously only parameter estimation was recognizing these values.
• Various improvements to the steady state task, including an additional Newton step to improve numerical stability.
