[Paraview] Getting line data into Paraview 3.10.0

[Lester Anderson]

Hello

I have tried replacing the windows path structure with Unix style with no effect so I am not sure what the issue is ?

I can upload the whole sample file to test if that would help?

As I can tell the the script will search for the delimiter of ">" to find each segment which is clear from the input file, but for whatever reason it seems not to be able to even locate the file.

Cheers

Lester

I recommend always using Unix style paths when trying to open files even when on windows.

is it because you are using "\" in your path ?

It seems that your command to open the file is wrong..
