Example implementation of the nifti-zarr specification in Python

Convert a nifti file to a nifti-zarr storage.

from niizarr import nii2zarr
nii2zarr("path/to/nifti.nii.gz", "s3://path/to/bucket")

Convert a nifti-zarr storage to a nifti file. The pyramid level can be selected with level=L, where 0 is the base/finest level.

from niizarr import zarr2nii
zarr2nii("s3://path/to/bucket", "path/to/nifti.nii.gz", level=0)

Load a nifti-zarr into a nibabel.Nifti1Image object.

from niizarr import zarr2nii
nivol = zarr2nii("s3://path/to/bucket", level=0)
