Python · sddb client
from sddb import Catalog

ds = Catalog().dataset("h4ZFYd8paMPmpqXc0000")
ds.elements()          # inspect without downloading
sdata = ds.to_sdata()  # cached locally, reused
print(sdata)
Python · lamindb

Needs pip install lamindb and network access to the Lamin database, which is limited during the alpha. If it fails, use the Client tab.

import lamindb as ln

db = ln.DB("scverse/spatialdata-db")
artifact = db.Artifact.get("h4ZFYd8paMPmpqXc")   # stem uid: Lamin resolves it to the latest version

sdata = artifact.load()   # cache, then load into memory
group = artifact.open()   # stream without downloading
path  = artifact.cache()  # sync into the local cache, returns the path
Shell
# sddb client: download the .zarr into data/
sddb-cli download h4ZFYd8paMPmpqXc0000 --dest data/

# or lamin: cache the dataset and print its local path
lamin load https://lamin.ai/scverse/spatialdata-db/artifact/h4ZFYd8paMPmpqXc

# or connect once, then load by uid
lamin connect scverse/spatialdata-db
lamin load artifact --uid h4ZFYd8paMPmpqXc
