    I want to split my ROIs into training and testing, but I want to do it multiple times and get multiple results for the classification, so I created an array where the value is the SplitFraction for the SplitExamples Task and connected it to an iteration task then on to the SplitExamples Task. In ENVI Modeler I import my raster and ROIs, use ExtractExamplesFromRaster then ShuffleExamples after that, I connect it to SplitExamples. I don't understand how to select only the testing ROIs from the output to connect it to the TrainClassifier task and whether it splits each group based on how many values are in the array, so if I had 10 values in the array, would it produce 10 different training and testing splits.

    Is there a way to convert ENVIEXAMPLES to ROIs?
