The "zarr" data source allows Neuroglancer to directly read zarr
format arrays, using the following data source URL syntax:
zarr://FILE_URL, where FILE_URL is a URL to the directory containing the .zarray metadata file
using any supported file protocol.
Alternatively, FILE_URL may be a URL to the directory containing the .zattrs metadata file that
specifies an OME-NGFF multiscale dataset.
Multiscale metadata versions 0.4, 0.5-dev and 0.5 are supported.
If the zarr array uses / rather than the default of . as the dimension separator in chunk keys,
you can either specify the separator as the dimension_separator member in the .zarray metadata
file (preferred) or use a data source URL of zarr://FILE_URL?dimension_separator=/.
Supported compressors:
- raw
- gzip
- zlib
- blosc
Filters are not supported.
Dimension names may be specified using an _ARRAY_DIMENSIONS attribute,
as defined by xarray.
Supported data types (little and big endian):
- uint8
- int8
- uint16
- int16
- uint32
- int32
- uint64
- float32
