[Paraview] NaN values

[Doina Gumeniuc (224252 MAHS)]

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. Thank you!

Hi

Can you share your dataset ?

Thanks,

Hi Mathieu,


I am using a vtk poly data file, which when I load in paraview, it gives me error (paraview just stops working). I was thinking it is because of my NaN values.

Hi

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

Best,

Hi all,


I have a file with NaN values in almost every column and row. 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?

Thank you!
