Temporal Dimension Semantics in 2D + Time Image Series Written Out As 3D Image

Oh, doing further searching and found this post:

How to write a custom Tag to an image (NRRD or other) header

The following question was asked on the ITK user mailing list: I can’t find any possibility to add a field (custom or not) into a nrrd header. The NrrdImageIO doesn’t allow it (or I missed it). Is someone know how to do that? Here is an short example to add a tag to a header (more specifically to add a key/value pair to the metadata dictionary of an image: CMakeLists.txt: cmake_minimum_required(VERSION 3.0) project(metadataNRRD) find_package(ITK REQUIRED) include(${ITK_USE_FILE}) add_e…

I’m doing attempting this sort of thing now, setting kinds tags:

img.GetMetaDataDictionary()['kinds'] = 'time domain domain'

But this doesn’t end up in the output .nrrd header metadata. I still end up with:

kinds: domain domain domain

I’ve tried setting the kinds tag in MetaDataDictionary dictionaries in all these:

1. the image,
2. the writer filter,
3. the image IO (NrrdImageIO).

And yet, somehow, in the output I don’t see the time domain.

Would you suggest what I’m doing wrong here?
