Support of OME-NGFF images without Z or T dimension #172

Closed berombau closed 9 months ago

berombau commented 11 months ago

Use Case

OME-NGFF images can currently be viewed, but only if they have Z and/or T dimensions. viewing 10501752.zarr does not work viewing 5025553.zarr works (although XY view instead of 3D view does not work either)

list of OME-NGFF samples

0.4     10501752.zarr 464   494         50      XYC             
0.4     5025553.zarr 2500   2500    1   27  1   XYZCT

Solution

XYC datasets are opened in a working XY view or XYC datasets are changed to XYZCT datasets by the viewer automatically.

Alternatives

Adding dummy Z=1 and T=1 dimensions when creating the datasets is possible, but not practical for users.

Thank you for reporting this. I'm going to look into it today and see if I can get it fixed quickly. I believe we do have an implicit assumption of at least XYZ dims but I'm sure we can implement some form of your suggested solution to all these to load properly.
