Configuration file !! #18

I put all the parameters and the input and output files paths. But when the algorithm reaches this instruction 'ficheroTree = parameters.getOutputFile(0);' in the class DT_oblicuo(). An error appears as follows:

Exception in thread "main" java.lang.NullPointerException
    at java.io.FileOutputStream.<init>(Unknown Source)
    at java.io.FileOutputStream.<init>(Unknown Source)
    at org.core.Fichero.escribeFichero(Fichero.java:30)

    at DT_oblicuo.execute(DT_oblicuo.java:107)
    at Main.execute(Main.java:18)
    at Main.main(Main.java:36)

My configuration file is as follows: image

In your configuration file, an output file is missing in the outputData field. There must be three output files: training predictions, test predictions and the representation of the decision tree.

This is an example of a configuration file obtained with KEEL 3.0 (2018-04-09):

`algorithm = Evolutionary Oblique DT Induction inputData = "../datasets/iris/iris-10-1tra.dat" "../datasets/iris/iris-10-1tra.dat" "../datasets/iris/iris-10-1tst.dat" outputData = "../results/DT_Oblique-C.iris/result0s0.tra" "../results/DT_Oblique-C.iris/result0s0.tst" "../results/DT_Oblique-C.iris/result0s0e0.txt"

seed = 1286082570 Number of Total Generations for the GA = 25`

Okay, thank you.
