Hello I am new here, and maybe this is a stupid question, but I have a problem with the operator W-GeneralizedSequentialPatterns. No matter what format my example source has (access, csv, arff), i always get the same message:

W-GeneralizedSequentialPatterns caused an error: weka.core.NoSupportForMissingValuesException: weka.associations.GeneralizedSequentialPatterns: Cannot handle missing values

The problem is that my data doesn't contain missing values. I even tried a totally simple arff-file with only one attribute and one data row and i stll get this message.

I would be very grateful for an answer.

    Unfortunately I can't really give you a hint, because I'm not familiar with the implementation of the weka learners. But I will ask around abit and get back to you, if I get some usefull answers :)
