ngff-zarr
A lean and kind Open Microscopy Environment (OME) Next Generation File Format (NGFF) Zarr implementation.
✨ Features
- Minimal dependencies
- Work with arbitrary Zarr store types
- Lazy, parallel, and web ready -- no local filesystem required
- Process extremely large datasets
- Conversion of most bioimaging file formats
- Multiple downscaling methods
- Supports Python>=3.11
- Reads OME-Zarr v0.1 to v0.6 into simple Python data classes with Dask arrays
- Optional OME-Zarr data model validation during reading
- Writes OME-Zarr v0.4 to v0.6
- v0.6 adds RFC-5 coordinate systems and transformations
- Sharded Zarr stores
- Zarr I/O backed by zarrista / Rust zarrs (Python) or zarrita (TypeScript) -- no zarr-python dependency; OME-Zarr 0.4 (Zarr v2) outputs stay readable by zarr-python 2 and 3, and 0.5+ (Zarr v3) by zarr-python 3
- Anatomical orientation metadata (RFC-4)
- OME-Zarr Zip (.ozx) file support for single-file OME-Zarr datasets (RFC-9)
- High Content Screening (HCS) support for plate and well data
- Model Context Protocol (MCP) server for AI agent integration
