[Paraview] Analyzing and animating a series of CSV tables

[Einat Lev]

Hello all!

I have a set of CSV data files (named file.csv.1, file.csv.2, file.csv.3 and so on), that I want to load and analyze in Paraview. Each file has 100000 lines, and there is a total of 10 files. The loading works fine. Converting to Structured Grid also works fine.
I display the colored surface, but when I get to the last frame, an error pops up, saying that 

The input table must have exactly 1000000 rows. Currently it has 11000000 rows.

If I then apply a contour filter to get an isosurface, the isosurface shows, but I also get warnings:

Generic Warning: In /Users/kitware/buildbot-slave/paraview-bigmac-osx-shared-release_osx10_7_qt4_superbuild/source-paraview/VTK/Common/Core/vtkMath.cxx, line 1344

Any suggestions? The end goal is an animation of the isosurfaces over the duration of the sequence.
