Hey, I’m having problems loading a vtk series in paraview.
My meta file frame.vtk.series looks like this:
```auto
{
"file-series-version" : "1.0",
"files" : [
{ "name" : "frame_0.vtk", "time" : 0.0 },
{ "name" : "frame_1.vtk", "time" : 1.5 },
{ "name" : "frame_2.vtk", "time" : 2.3 },
{ "name" : "frame_3.vtk", "time" : 3.8 },
{ "name" : "frame_4.vtk", "time" : 4.0 }
]
}
```
I can open the files individually without any problem. But when I try to open the jason file I get asked for a reader. In the popup list I can’t find a vtk Reader.
Help is very much appreciated!!

name your file `file.vtk.series`

Hello Mathieu, thank you for your reply. I changed the jason file name to file.vtk.series but I still get asked to select a reader.

As I said, name your file `file.vtk.series` not `file.vtk.series.json`.

Thank you so much! I thought it still has to be a .json file. Everything works fine now
