                      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
