Sequential Rule Mining - Now What?
After we apply the GSP operator to a proper dataset, it is not obvious to me what we can do with the results passed to the port pat, or, the GSPSet.
Simply, how can we analyze the resulting rules for support, confidence, etc, after applying the GSP operator? It's not obvious what operator would go next, and Create Association Rules is looking for a Frequent Itemset generated by FP Growth.

In the Advanced Reporting Extension, there's an operator called "Extract Tables". It should be able to get the data from the visualization and convert it into a standard Example Set so that you can apply any operator that can process regular data.Greetings,Sebastian7

it's really the question what you are trying to achieve. Could you give us some hints?
I appreciate the replies @mschmitz and @land , but I guess I lost as to what operators can be used after GSP in RapidMiner.
