A directory containing CT and RWV modality files causes some errors, data can't be shared but is available from @kleesiek or @nolden .
Two things are already investigated:
- gdcm 2.6 doesn't handle RWV at all, gdcm 2.8 seems to have better support.
- Sort failure for some datasets should not necessarily break the complete reading. The CT files of the mentioned dataset are perfectly readable if copied to a separate folder.
