Test Data Preprocessing

[htjb]

I currently think that the preprocessing for the test data is not right and this will impact the early stopping. Below is an example of the preprocessed training data with various combinations of AFB and resampling on (division by the standard deviation of the training data is on by default here)

and the same for the test data

Clearly something is not right here. It looks like the AFB subtraction is never applied to the test data.

Will open a PR to debug and fix.
