It seems a vtp file has errors, from my point of view, T_PLIC_left seems to be a empty file. I dont know how to settle this problem,
by the way, other errors show but I dont know which line of code bring this, such as this:
If you don’t expect that file to contain some valid content then you can ignore this error. VTK may report it as an error when you attempt to read or write an empty file, while it may be normal that a fiber is empty.
I would suggest you to report this error to the SlicerDMRI extension repository. You can add a note that a possible fix would be to apply the same technique as it is done in the model storage node: use the SkippedNoData write state to indicate that the file is expected to be empty.
