title: Train and test set are not compatible error in weka?
body: <p>I'm trying to test my model with new dataset. I have done the same preprocessing step as i have done for building my model. I have compared two files but there is no issues. I have all the attributes(train vs test dataset) in same order, same attribute names and data types. But still i'm not able to resolve the issue. Both of the files train and test seems to be similar but the weka explorer is giving me error saying Train and test set are not compatible. How to resolve this error? Is there any way to make test.arff file format as train.arff?  Please somebody help me.</p>
