ADTree Output in Apply Model?

I am running the Weka ADTree algo on a binary classification dataset which if I understand correctly will output a value between 0 and 1 and will classify 0 if <=.5 and 1 if >.5

If I am wrong please correct me.

My question is whether there a way to see the actual value computed by the model in the apply model output?

I only see the prediction and the confidences now.

Also, how is the confidence computed from the model value?
