Mismatch between Validator and Vizarr viewer

[JensWendt]

Hi ,

I just checked out the latest https://deploy-preview-53--ngff-challenge.netlify.app/
and realized the NGFF-validator seems perfectly fine for my Lightsheet image but the proposed Vizarr viewer throws an error: Error: server replied with "Group is missing multiscales specification." when loading the resource
When I add /0 at the end, it works fine (except the fucked up B&C settings for the channels 😄 )
Is there something I can add/change to make it work properly?

Ah - Thanks for the feedback. Hmm - I realise I don't have the information stored in the CSV to know whether to add a /0 to the URL for vizarr. I actually look that up for each zarr as part of the Thumbnail generation, so I could use that to fix the link. Alternatively I could add into the csv the path-to-image, which would improve performance of thumbnail loading.
I'll look into it...

Adding the path-to-image seems tricky -- in this case it works because there's only one image, but then you lose the RO-Crate, no?

I guess what I mean is adding a relative path/to/thumbnail/zarr.json and not changing the original url/to/image.zarr.
This would also fix the thumbnail for images where the bioformats2raw series is not /0. I'm currently making the assumption of /0 for thumbnails (so I don't have to load the XML just to render a thumbnail) but it breaks like https://deploy-preview-36--ome-ngff-validator.netlify.app/?source=https://radosgw.public.os.wwu.de/n4bi-goe/Platynereis-H2B-TL.ome.zarr

Gotcha.
