Hi Chris,
when you use the batch preprocessing script PI selects the best preferences by it´s own. So you don't have to think of this. If you want to calibrate by hand you can see the preferences below. If you click the pure raw button everything is set to the best.
I think all images that the batch preprocessing creates are sometimes helpful, but if you really don't like it, deactivate "Export calibration files" at the right side.
In most cases I think you do not need the ABE. IMO DBE works better and you have more control over it.
Greetings
Tobias
