hi!
i have created a model using batched validation, is there a way to apply this model to non-batched data?

Here is the sample process I created 

<?xml version="1.0" encoding="UTF-8" standalone="no"?>

    The model that comes out of an operator of X-val uses the entire dataset. It's irrelevant if you used batch x-val or regular x-val. Store the model or write it to a file. Then you can apply it to a dataset with the same structure.
