Cross validation and getCurve()

Hi all,

I have the following question when I am using Weka for my Project:

I use the cross validation to do the evaluation:
    Evaluation evaluation = new Evaluation(trainInstances);
    evaluation.crossValidateModel(scheme, testInstances,10);

I don't know how to get the Prediction data from the above evaluation
variable for the getCurve() function to do the ROC analysis. Do I need to run the
getCVPredictions() again to get the Prediction for the getCurve() function?

Could anyone help me out?

Appreciate your help!
