docs(ome-zarr): say that the Direction matrix travels in the attributes sidecar - #190
Conversation
…es sidecar write_ome_zarr takes spacing and origin as keywords, and the Direction only inside ``attributes``, which the docstring did not say. A caller who passes the first two and not the third gets a store that reads back axis-aligned, and a registration run on such a pair returns its field in that frame: on an LPS pair, mirrored about the origin, and zero everywhere once carried back to the store's own frame. One paragraph names the sidecar and that consequence.

In `@konfai/utils/ome_zarr.py`:
- Around line 837-838: Update the documentation near ome_zarr_attributes() to
state that the identity-matrix fallback occurs when the sidecar attributes lack
a Direction entry, including the resulting LPS/axis-aligned frame consequence;
do not imply the entire sidecar must be absent.
- Around line 836-838: Update the write_ome_zarr docstring to document spacing
and origin as keyword-only arguments, explicitly noting that both must be
supplied by name because they follow the * separator.

836-840: 🎯 Functional Correctness | 🟡 Minor | ⚡ Quick winThe new statement that an omitted
Direction“reads back as the identity” is too broad:read_ome_zarr_data_slicereturns the rawattributessidecar and does not add that key. Scope the identity default to theome_zarr_attributes/image conversion path, or document that raw metadata still omitsDirection, so callers do not rely on an identity matrix that is absent.🤖 Prompt for AI Agents
