Exeception when saving as .zarr

[dmilkie]

I succeeded in saving a 704x1800x3814 unsigned 16-bit image to .n5 and .h5. When I try to save as .zarr I get the following error:

(Fiji Is Just) ImageJ 2.3.0/1.53q; Java 1.8.0_322 [64-bit]; Windows 10 10.0; 9717MB of 48813MB (19%)

@dmilkie ,

That's a bug, thanks for reporting. Could you try writing the dataset name as /test instead of test, and see if that helps.

[dmilkie]

Yes. That way works! (I'm using Windows.)

[bogovicj]

@dmilkie Awesome, thanks for the follow up! This still needs fixing though.

[bogovicj]

This was fixed by https://github.com/saalfeldlab/n5-zarr/commit/2f4dc63120a0cd24c4d7fefae93b7961234c0484 and will work in Fiji once I update it. I'll do that shortly, and then will close this issue.
