What is data file format for operator W-GeneralizedSequentialPatterns
Error in: W-GeneralizedSequentialPatterns(W-GeneralizedSequentialPatterns)
W-GeneralizedSequentialPatterns caused an error:
Weka.associations.GeneralizedSequentialPatterns: Cannot handle missing values!
However I have no idea about the data file format that Weka-GeneralizedSequentialPatterns need.
I tried pure text file, csv file, xls file and spss file, everything caused the same error messge.
Even I delete all the contents of the file, and only leave one word such as "abcd", the same error message appears.
Please help me if you know how to solve the problem.
Thanks in advance.
