We need to sort out axis labeling soon

[matthew-brett]

I've just merged #255 - which assumes that the spatial axes are the first three.

This is true of Nifti and Analyze, but not - say - of MINC.

See discussion at #255 (comment) and https://github.com/nipy/nibabel/wiki/BIAP6#general-solution-associating-axes-and-labels

Before the next release we should work out how to specifically identify axes, either by forcing MINC into the NIFTI convention, or by specific labeling.

I'm leaning towards depending on datarray for this.

I'm leaning towards depending on datarray for this.

This means you have considered, and decided against, https://github.com/pydata/xarray ?

[matthew-brett]

Yes, at least for now. xarray depends on Pandas, and nibabel is a python-only package at the moment.
