PyPI - Version PyPI - Python Version Python CI Testing DOI Documentation Status

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
