Hi Efi What are the field names in your shapefile? Are you sure it contains "area"? You can see it in QGIS (right click -> "Open attributes table" I think).
Another debug thing you can try is calling from the command line (with otbcli_VectorClassifier...) to see if you get the same error.

In Monteverdi all works fine. I think there must be a mistake in the code when defining the 'cfield' and/ or the 'feat' parameters. Here is the code (also attached as .py file): import otbApplication VectorClassifier = otbApplication.Registry.CreateApplication("VectorClassifier") VectorClassifier.SetParameterString("in", "zonals_22.shp") VectorClassifier.SetParameterString("model", "model.txt") #VectorClassifier.SetParameterString("cfield", "class") #VectorClassifier.SetParameterString("feat", "area", "perimeter", "complexity", "_mean", "_std", "pmr") VectorClassifier.SetParameterString("out", "out4.shp") VectorClassifier.ExecuteAndWriteOutput() Output is: itk::ERROR: ListViewParameter(0000000001023A20): Cannot find area Any suggestions?
