Remote URLs

Stream OME-ZARR data directly from remote servers without downloading anything.

Streaming turns every chunk into an HTTP range request, so what you serve from matters more than how fast your connection is. Your OME-ZARR Storage Setup Is Slowing You Down covers which storage handles that pattern well, and why an NFS or SMB mount usually does not.

Opening a Remote Dataset

1. Click Open Image on the landing page
2. Paste an OME-ZARR URL into the URL field
3. Click Load from URL

The viewer streams tiles on demand. Only the data you're currently viewing is fetched.

Public Data Sources

The Image Data Resource (IDR) hosts thousands of public microscopy datasets in OME-ZARR format. Browse the IDR, find a dataset, and copy its ZARR URL to open it in Find Nuclei Viewer.

Example URLs:

https://uk1s3.embassy.ebi.ac.uk/idr/zarr/v0.4/idr0079A/idr0079_images.zarr
https://uk1s3.embassy.ebi.ac.uk/idr/zarr/v0.4/idr0001A/2551.zarr

CORS Requirements

Remote servers must have CORS enabled for the viewer to access data. Most public OME-ZARR servers (IDR, BioImage Archive) already support CORS.
