input [output]
Convert a Blosc2 .b2nd file (NDArray) into a Zarr array.
positional arguments:
input Path to input .b2nd file
output Path to output .zarr array (default: <input>.zarr)
options:
-h, --help show this help message and exit
-o OUTPUT_OPT, --output-path OUTPUT_OPT
Optional explicit output path (overrides positional output)
-c CHUNKS, --chunks CHUNKS
Zarr chunk shape, e.g. '10,1000,1000' (default: inherit from .b2nd)
--shards SHARDS Zarr shard shape (for sharded arrays in Zarr v3)
--sharded Enable sharding automatically: map .b2nd chunks to shards, and blocks to
chunks
--codec {auto,blosc,zstd,lz4,lz4hc,blosclz,zlib,gzip,none}
Compression codec for Zarr (default: 'auto', matching .b2nd cparams)
--clevel CLEVEL Compression level (0-9, default: inherit from .b2nd)
--shuffle {auto,noshuffle,shuffle,bitshuffle}
Shuffle filter (default: 'auto', matching .b2nd filters)
--blocksize BLOCKSIZE
Block size in bytes for Blosc codec (default: inherit from .b2nd cparams)
--zarr-format {2,3} Zarr specification format (default: 3)
-b BUFFER_SIZE, --buffer-size BUFFER_SIZE
Max memory buffer size in MB for batch copying (default: 128)
-f, --force, --overwrite
Overwrite destination store if it already exists
--verify Verify array integrity (corner and sample equality check)
--full-verify Perform thorough element-by-element verification of all chunks
-v, --verbose Show detailed conversion information
-q, --quiet Suppress all progress and informational output
Examples:
blosc2-to-zarr cube.b2nd
blosc2-to-zarr cube.b2nd cube.zarr --chunks 20,500,500
blosc2-to-zarr cube.b2nd -f --verify --full-verify
blosc2-to-zarr cube.b2nd --codec zstd --clevel 3
blosc2-to-zarr cube.b2nd --sharded
