FS Error

I always get “FS error” when I trying to visualize a vtk file on paraview glance or itk-viewer.
What does this error mean and how can you please avoid it?
Thank you

What sort of vtk file are you looking at? Is it a file that has the “.vtk” extension? If the dataset is publicly shareable, could you share it?

Yes it’s publicly shareable but I got an error when I upload the vtk !

My ‘.vtk’ file is like that !

Thanks! I took a look, and the underlying error message is “Unsupported file”. We use itk.js to read those files, so the issue would be there.
