Filter certain traces based on event sequence

Hi there,

I my log file I have some traces which should not be considered. Those particular traces contain a certain sequence of events. How can I filter out all of those traces with that sequence (pattern abstraction?)?

    Hi Ralf,

    It is unclear on what you meant by filtering. If you are interested in selecting only those traces that contain the pattern (event sequence), then pattern abstractions plug-in can help you in that. However if you want to consider all traces that do not contain the event sequence, then it is not possible with pattern abstractions.

    I make an assumption that the event sequence repeats in multiple traces or within a trace.

    Best Regards,

    Hi JC, indeed, I want to consider all traces that do not contain a certain sequence of events. This sequence appears in multiple traces.

    Hi Ralf,

    I think this is possible with an LTL formula. If the standard formula's don't contain a sequence of activities that is long enough then you can specify your own LTL formula's to fit your purpose.
    See the LTL documentation here to get started:
