From 01795a2aa5eb808ad230150804ed0291086ec24d Mon Sep 17 00:00:00 2001 From: dud8 <159498121+dud8@users.noreply.github.com> Date: Mon, 7 Sep 2026 13:55:20 -0400 Subject: [PATCH] docs: point the Zarr quickstart at a volume that exists in the bucket README.md:227 and examples/zarr_volume_access.py:35 open s3://vesuvius-challenge-open-data/PHerc0332/volumes/20231201141544-3.240um-70keV-masked.zarr/ That prefix is not in the bucket (HTTP 404 on .zattrs); the catalogue publishes that 2023 volume under https://data.aws.ash2txt.org with a samples/ prefix. The documented quickstart therefore fails on first run. Switched both to PHerc0332/volumes/20251211183505-2.399um-0.2m-78keV-masked.zarr/, the PHerc0332 volume actually in the bucket (HTTP 200 on .zattrs and 0/.zarray). --- README.md | 2 +- examples/zarr_volume_access.py | 2 +- 2 files changed, 2 insertions(+), 2 deletions(-) diff --git a/README.md b/README.md index 8facaba..aa99614 100644 --- a/README.md +++ b/README.md @@ -224,7 +224,7 @@ import matplotlib.pyplot as plt s3 = fsspec.filesystem('s3', anon=True) # Public bucket; set anon=False if using credentials # Open an OME-ZARR volume from S3 -store = s3.get_mapper('s3://vesuvius-challenge-open-data/PHerc0332/volumes/20231201141544-3.240um-70keV-masked.zarr/') +store = s3.get_mapper('s3://vesuvius-challenge-open-data/PHerc0332/volumes/20251211183505-2.399um-0.2m-78keV-masked.zarr/') root = zarr.open(store, mode='r') # Access data at different resolution levels diff --git a/examples/zarr_volume_access.py b/examples/zarr_volume_access.py index b6da33b..8e88e16 100644 --- a/examples/zarr_volume_access.py +++ b/examples/zarr_volume_access.py @@ -32,7 +32,7 @@ s3 = fsspec.filesystem('s3', anon=True) # Public bucket; set anon=False if using credentials # Open an OME-ZARR volume from S3 -store = s3.get_mapper('s3://vesuvius-challenge-open-data/PHerc0332/volumes/20231201141544-3.240um-70keV-masked.zarr/') +store = s3.get_mapper('s3://vesuvius-challenge-open-data/PHerc0332/volumes/20251211183505-2.399um-0.2m-78keV-masked.zarr/') root = zarr.open(store, mode='r') # Access data at different resolution levels
