So it is not currently possible to do what you are asking with the NDFileHDF5 plugin, i.e. store arrays of different sizes from different sources in the same HDF5 file.

One of the ways you *might* do this is to write each of those arrays

into a separate HDF5 file and then use the "external file link" process

to link that data back into the "master" NeXus file.

See:

That page has a broken link to be fixed shortly. This is the correct

link:
