brainglobe-atlasapi V3 compatibility: changes to on-disk format #18

Description

@IgorTatarnikov

Hello from the BrainGlobe team!

We're just about to release a new major version of brainglobe-atlasapi. There are minimal changes to the Python API, however, the structure of the atlases on disk has been altered significantly. Array-based data is now stored as OME-Zarr, and meshes are in the neuroglancer precomputed format. Atlas components are now reused across atlases, and fetched lazily. Atlases are now stored in .brainglobe/brainglobe-atlasapi by default. Existing atlases (e.g. .brainglobe/allen_mouse_25um) can be safely deleted. See the blog post for more details.

You can install the current pre-release version with pip install brainglobe-atlasapi==3.0.0rc2.

Please contact us on Zulip if you encounter any issues with the new version!
