How can I extract test data, validation data and testing data from my trained network?

I have used a feedforward backprop to train a network (ANN). I would want to know how to extract the training, validation and testing data sets respectively.

Thank you.

Can you tell us the function you used to train the network?

It seems like you trained the model BEFORE you divide your data into training, val and testing sets?
