percentage split

Hi,


I have loaded a full dataset->applied attribute selection in filters with default parameters->classify->SMOreg->test options chosen as %split=75%
Result i obtain is for test set,but if i want to see training set accuracy also, how to do with % split?

Also,
plz tell me, which is the better way - using 2 separate files (training and test file) or directly load one common file and use % split?
