Did you try SetParameterStringList?

Hello Victor, thanks for replying. It does run form the command line. But I can't figure out the correct syntax for python. When the "feat" line is omitted in python, it does run but all polygons are classified in one class, which is wrong... In the command line I also specify all the attribute table columns to be used, as a 'list', like: - feat area perimeter complexity etc... And I haven't found any sample code that includes more than one features. Do you have any idea where to look for an answer? Also posted a question on GIS stack exchange with no results yet.. Regards, E - feat area perimeter complexity etc.. jhm On Tue, Dec 4, 2018 at 5:09 PM Poughon Victor <[email protected]<mailto:[email protected]>> wrote: 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?
