[Paraview] Paraview 3.14.1 Tecplot Reader Errors

[Richard GRENON]

Hello

I don't know how to make this with a command line, but you may read your 
ASCII file, then use the menu File->Save Data, select the VTK file type, 
and you will have a popup window with some options:
- Data mode: ascii, binary or appended (default).
- Compressor: None (default) or Zlib

May be this could be automated with a Python script. Browse the mailing 
list: there are several subject about converting ascii to binary.

Also you make look here for Python vtk writers :
