No warning when the manually specified table doesn't actually annotate the labels element

[timtreis]

I forgot to set the spatialdata_attrs so the function was generating random colors for my labels - instead it should've failed and told me that the table doesn't annotate that labels object.

Correct plot after setting it:

@timtreis I am having the same issue, could you explain how you are supposed to set the spatialdata_attrs to make this work? I've tried replacing the table.uns['spatialdata_attrs']['region_key'] with 'leiden', but it throws the error (Regions in the AnnData object and leiden do not match.)

Hey @VikramGanesanjs,

here you can find an example on how to manually set it: https://github.com/scverse/spatialdata-notebooks/blob/main/notebooks/examples/sdata_from_scratch.ipynb

the tl;dr is like this:

table.uns["spatialdata_attrs"] = {
    "region": "<name of the sdata element it annotates>",  
    "region_key": "<column in adata.obs that will link a given obs to the elements it annotates, same entry as region>",
    "instance_key": "<column that matches a given obs in the table to a given circle by id>",
}
