Update: I've corrected the download location for this program. It is available from: here
All tools for Bifurcation analysis have always been a bit difficult to use. This was the motivation for a new frontend to Auto 2000. Below a screenshot showing the stability of BioModel #203. All that was needed was to load the model, set the Parameter to ‘A’, change the End value to ‘100’, as i wanted to sweep the range [0:100] and then to press run. In the output i noticed that the value never quite reached ‘100’ and thus i increased the number of points. All in all, really easy to use.
Of course it needs more testing, if you are interested in it you can download it. As always it will require SBW to be installed. The program also works nicely on Linux (tested with Ubuntu 8.10), you need to drop me a line, and i can wrap that up. So far I did not have much luck getting it to run on OS X.
