Data Resources#

Looking for test data? IDR Samples aims at covering the different corners of the specification.

After this quick reference, you can find a diverse set of data resources in OME-Zarr format, illustrating the range of scientific stories enabled by the format.

Do you have a data resource in OME-Zarr format that you would like to share? Is there something missing? Please submit an issue or pull request to update this list.

Datasets#

These are datasets available in OME-Zarr format, hosted in various locations. They represent some of the different scientific stories enabled by OME-Zarr.

Resource

Description

Open SciVis source

A collection of of volumetric datasets in OME-Zarr format, including several CT scans.

Atlases#

These are “atlas”-like datasets, which provide a comprehensive view of a particular biological system. The metadata-rich, streaming-friendly nature of OME-Zarr makes it ideal for sharing and visualizing large, complex datasets that are often associated with atlases.

The WebAtlas pipeline (Li et al, 2024) demonstrates how OME-Zarr can be used in the context of deploying such atlases in the context of spatial transcriptomics. The examples, however, cover also other types of data, including volumetric electron microscopy, expansion microscopy and light sheet imaging.
