Hi! Yes, I of course understand your point. There is a bit of a problem though: In reality, this file is much more bigger and deleting the NaNs by hand is not an option (also I am trying to make it all happen automatically). If I ask matlab to delete the zeros from my file, the shape of the matrix will change, so the only solution I found so far is to replace the zeros by NaNs in matlab, which gives me error in paraview, for the reason you, Moreland, explained.
So my question would be again, is it possible to replace it with anything else?

(I just tried it. It worked fine.) However, you are trying to introduce NaN’s in a list of integer connections, which is just wrong on many levels. However, I do not see why you need NaN at all. The LINES connectivity list allows you to vary the length of the line chain. It looks like you can solve your problem by simply not writing out the NaN’s in the fill. In the example you sent us, I presume that you mean to have 4 line cells with 2, 3, 2, and 2 vertices, respectively. The following should be the correct representation of that: LINES 4 13 2 0 1 3 1 2 3 2 3 4 2 4 5 -Ken From: ParaView <paraview-boun...@paraview.org> on behalf of "Doina Gumeniuc (224252 MAHS)" <224...@via.dk> Date: Monday, November 13, 2017 at 12:55 PM To: Mathieu Westphal <mathieu.westp...@kitware.com>, "paraview@paraview.org" <paraview@paraview.org> Subject: [EXTERNAL] Re: [Paraview] NaN values Hi Mathieu, Sadly I can not import the whole file, but here is an example: LINES 4 13 2 0 1 NaN 3 1 2 3 2 3 4 NaN 2 4 5 NaN I make the vtk file in matlab by extracting the information from a .dat file. Originally, instead of NaN there are zeros, but I just need blanks without changing the shape of the matrix, which is why I use NaN, but it gives me error in paraview. I hope it explains what I mean.

If you are reading a .csv file, the correct string that is interpreted as NaN is "nan" without the quotes.

The integer numbers represent which points should be connected by lines, therefor I can not replace NaN with zeros because it will interpret it as Point with ID 0. Is there any way I can replace this NaNs with something which paraview reads as blanks?
