Output of "Evaluate Process Tree"-Plugin is not accessible

edited January 2017 in - Usage
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?


  • Dear Martin,

    Could you clarify which ProM version you are using? ProM lite 1.1, ProM 6.5, ProM 6.6 or the ProM nightly build?

    I have the same problem withplugin "Evaluate Process Tree" and i'm using ProM version 6.6
  • Hi Martin,

    If you have a process tree, there are several plug-ins to evaluate it:
    - 'visualise deviations on process tree'. This will compute an alignment and can visualise the differences, much like the Inductive visual Miner (it won't give you a number, though)
    - use a plug-in 'compute projected fitness and precision'. This will compute a fitness and precision value; the speed and accuracy of the comparison depend on the chosen number (I've chosen 2 most times).
    For more details about this plug-in, please refer to
    - convert the process tree to a Petri net and use the alignment plug-in 'replay a log on Petri net for Conformance analysis'.
    - 'evaluate process tree' (I'm not aware of the working of this plug-in).

    Kind regards,
