Scientific Databases

Relay includes connectors to four major public scientific data repositories. You can browse, search, and mount datasets directly into your viewer — no download required.

DANDI Archive

DANDI is a public archive for neurophysiology and behavioral data.
  • Search neurophysiology and behavioral datasets
  • Mount NWB files via HTTP range streaming (no full download needed)
  • Mount OME-Zarr and LINDI files
  • Pagination — cursor-based, 25 results per page
  • Save to Relay Drive — download datasets for offline access
  • Signed URLs — 6-hour TTL for streaming access

IDR (Image Data Resource)

IDR is a repository of reference microscopy datasets.
  • Browse curated microscopy datasets
  • Mount OME-Zarr from UK1S3 server
  • Metadata display — SizeX/Y/Z/C/T, pixel type
  • Thumbnail previews in search results
  • Conversion option — convert to OME-TIFF if Zarr is unavailable

Allen Brain Cell Atlas

The Allen Brain Atlas provides reference brain datasets. Curated datasets include: Datasets are accessed via direct S3 URLs and loaded as Zarr or Neuroglancer Precomputed tiles.

AWS Open Data

Relay includes connectors to select AWS Open Data datasets:

Open NeuroData

HuBMAP

Earth observation

Mount by URL

You can mount any dataset by providing a direct URL:
  • Zarr — any HTTP-accessible Zarr store
  • NWB — any HTTP-accessible NWB file
  • Neuroglancer Precomputed — any Neuroglancer-compatible tile source
Simply paste the URL into the database mount dialog and Relay will auto-detect the format.

Drag and drop

You can drag dataset entries from the database browser directly onto a pane to load them instantly. This works across all four database connectors.
