tiledbsoma.io.append_obs

tiledbsoma.io.append_obs(exp: Experiment, new_obs: DataFrame, *, obs_id_name: str = 'obs_id', registration_mapping: ExperimentAmbientLabelMapping, context: SOMATileDBContext | None = None, platform_config: Dict[str, Mapping[str, Any]] | object | None = None) → str

Writes new rows to an existing obs dataframe. (This is distinct from update_obs which mutates the entirety of the obs dataframe, e.g. to add/remove columns.)

Example:

rd = tiledbsoma.io.register_anndatas(
    exp_uri,
    [new_anndata],
    measurement_name="RNA",
    obs_field_name="obs_id",
    var_field_name="var_id",
)

with tiledbsoma.Experiment.open(exp_uri, "w") as exp:
    tiledbsoma.io.append_obs(
        exp, new_anndata.obs, registration_mapping=rd,
    )
