File System

The filesystem implementation is a concrete implementation of the abstract copick API that reads and writes data to/from any storage supported by fsspec. The filesystem implementation is defined in the copick.impl.filesystem module.

Metadata Models

copick.impl.filesystem.CopickConfigFSSpec

Bases: CopickConfig

Copick configuration for fsspec-based storage.

Attributes:

  • overlay_root (str) –

    The root URL for the overlay storage.

  • static_root (Optional[str]) –

    The root URL for the static storage.

  • overlay_fs_args (Optional[Dict[str, Any]]) –

    Additional arguments for the overlay filesystem.

  • static_fs_args (Optional[Dict[str, Any]]) –

    Additional arguments for the static filesystem.

Data Entities

Get the zarr store for the object.

Returns:
