When using the Plugin "Evaluate Process Tree" in ProM I cannot do anything with the result. It's not possible to visualise it or to access it. Is this behaviour intended or not? I want to evaluate the fitness of my process tree with regard to a log file. I also found a Plugin named "compute projected fitness and precision". Would this plugin be usable too? If yes, there are a lot of variations of it, ranging from 2 to 9 activities. What is the difference between these variations?
