Hello All, If after you have successfully plotted in Paraview the results loaded from VTK or Silo files you then try to save the data using “File/Save Data …Ctrl+S” in regular ASCII TXT/CSV file format you get all the variables which were present in VTK/Silo files saved correctly in the saved table…

Hi @DanRR , and welcome ! [image] Dan: nodes or cells are completely missing no matter what other existing few options to save you try making the output totally useless. This is expected, .csv format does not support this kind of information. Just use another format. Best,

Interesting. So with VTK you can create the image of say your face but you can not get back and can not read the RGB color of each pixel of your image and place it into usual text format???

Depends on what you call “usual text format”. There are some ASCII file format supported in VTK, including the native .vtX family . But CSV has limitations, including not mixing Point Data and Cell Data in the same file.

You can ask user if he wants the saved data cell centered or node/interface centered. That is …

VTK is open source and your contributions are welcome: https://gitlab.kitware.com/vtk/vtk/ BTW using text based format is highly ineficient.

Hahaha ParaView people send you to VTK - the VTK people send you to ParaView and VisIt. :))))))) Sure, TXT files are slow and large but they are extremely useful for debugging. After debugging done, the best way is avoiding all these “formats” and use binary output which has speeds ~8GB/s and the …

All ParaView people are VTK people, @DanRR . If you want to improve the vtkDelimitedTextReader, the class is here: https://gitlab.kitware.com/vtk/vtk/-/blob/master/IO/Infovis/vtkDelimitedTextReader.cxx I agree that it needs improvement tbh and your idea of a new feature is actually not bad, writin…

[image] Dan: Then why your Ctrl+S doing output of Y values without appropriate Xes into txt file ? Looks like somebody did not know what he was doing ? :)) Whoa. Hang on a second. Are you saying you wrote out a csv/txt file that had the x coordinates but not the y (or z) coordinates? I have n…
