# Connect your tool: Lasagna Fields

The ten whole-scan fields in the public bucket read straight by URL, logged out, with no download step; villa's fields in the open data stream the same way from the run folders the Every field tab lists, and the other datasets download whole. The scans they came from are open data. The page is also an API and an MCP server that lists every field and makes a field for any box of any public scan.

Checked 2026-10-25. Generated from `connect.json` by `kit spaceconnect` in [ChaseHendrick/Scrolls](https://github.com/ChaseHendrick/Scrolls).

## A whole-scan field: PHerc0175A cos, level 1 (every 2nd scan voxel)

`https://huggingface.co/buckets/SharpMeow/lasagna-fields/resolve/PHerc0175A/representations/predictions/lasagna/20250521115057-lasagna-de45f011/PHerc0175A_cos.ome.zarr`

License: CC BY-NC 4.0 (derived from Vesuvius Challenge open data). Model output (villa lasagna at db3dbea2, scrollprize/lasagna at de45f011). grad_mag, nx and ny sit beside it, from level 2; PHerc0175A.lasagna.json in the same folder is villa's manifest. The other nine bucket scans: replace the scan and run folder as listed on the Every field tab.

import zarr

root = zarr.open_group("https://huggingface.co/buckets/SharpMeow/lasagna-fields/resolve/PHerc0175A/representations/predictions/lasagna/20250521115057-lasagna-de45f011/PHerc0175A_cos.ome.zarr", mode="r")  # OME-Zarr, zarr v2
a = root["1"]  # level 0 is full resolution; level L is 2**L times coarser
print(a.shape, a.dtype, a.chunks)
block = a[3186:3250, 2900:2964, 2200:2264]  # (z, y, x); reads only the chunks it touches
