Dear Paraview community,
I am trying to add the simulated time to a time series which would really make my animations more readable. I follow the JSON .vtr.series formatting, like so:
```auto
{
"file-series-version" : "1.0",
"files": [
{ "name" : "doab10.vtr", "time" : 60.0},
{ "name" : "doab20.vtr", "time" : 55793.8978},
{ "name" : "doab30.vtr", "time" : 98228.6093},
{ "name" : "doab40.vtr", "time" : 154165.5208},
{ "name" : "doab50.vtr", "time" : 199414.8669},
{ "name" : "doab60.vtr", "time" : 235629.7501},
{ "name" : "doab70.vtr", "time" : 269426.7697},
.
.
.
.
{ "name" : "doab2540.vtr", "time" : 9827530.7055}
]
}
```
I know about the comma sensitivity (e.g. no comma after the last entry). I have been able to use .vtr.series files generated with this script in Paravier 5.9, but since upgrading to 5.10 it stopped working, I can select the `doab.vtr.series` file in Paraview GUI but it then asks to select a reader (no `.vtr` reader option provided). Did this functionality change between 5.9 and 5.10, or am I overlooking something obvious?
Thanks in advance!
EDIT:
This is the output of my paraview server when I select the .vtr.series file:
```auto
luuk@holykauw ~ $ ./ParaView-5.10.1-egl-MPI-Linux-Python3.9-x86_64/bin/pvserver --force-offscreen-rendering

I attach the `.vtr.series` file. The .vtr data files are 600 MB each, so I just upload one below.

your files are incorrectly named:
`{ "name" : "doab400.vtr", "time" : 1010132.3158},`
```auto
$ ls doab*
doab_400.vtr doab.vtr.series
```
