include nifti headers

Any chance instead of empty raw data files, the files could include just the headers? It would be helpful to be able to pull metadata out of the headers for some test applications, even if the data aren't available.

How about using git LFS to get the actual files (upon request) from a public URL? See also my reply in this thread

@chrisfilo: I'm not sure, but does it matter? Most (all?) I/O tools will already fail if you try to read an empty nifti file, so I don't know that it matters why the failure occurs... one way or the other, the user has to expect that no actual processing of the images is possible.

@robertoostenveld the problem in this case is not how to pull only some files but not others, it's that some pybids functionality requires information contained in the nifti headers. So ideally I'd like to see headers in all the nifti files, but not include the actual image data.

The synthetic dataset by @effigies has the headers intact. (MRI)

For EEG and iEEG, those datasets with BrainVision data also have intact headers (mostly).

We don't have examples with intact headers for MEG.

I am still closing this issue now until it becomes urgent again.
