Hi, I would like to use the ExtractSelection filter by providing an ID List, as hinted in the doc http://www.paraview.org/ParaView3/Doc/Nightly/www/py-doc/paraview.simple.ExtractSelection.html?highlight=extractselection#paraview.simple.ExtractSelection
What is the correct syntax? First I tried : e = ExtractSelection(Sphere1, [1,2]) Traceback (most recent call last): File "<console>", line 1, in <module> File "R:\ParaView 4.4.0\lib\paraview-4.4\site-packages\paraview\simple.py", line 1520, in CreateObject raise RuntimeError, "Expecting a proxy as input." RuntimeError: Expecting a proxy as input. Then I tried: >>> selection = paraview.simple.IDSelectionSource(ContainingCells=0, FieldType >>> = "POINT", IDs = [0,1]) >>> e = ExtractSelection(Sphere1, Selection = selection) >>> e.UpdatePipeline() >>> e.GetDataInformation().GetNumberOfPoints() 1L #I expected 2 points and then, when I tried to visualize the result, I got: ERROR: In C:\bbd\b51c3c7f\source-paraview\ParaViewCore\ServerManager\Rendering\vtkSMParaViewPipelineControllerWithRendering.cxx, line 542 vtkSMParaViewPipelineControllerWithRendering (000000000C747260): Data cannot be shown in the defaulted render view!!
