AnnData.obs_vector(k, *, layer=None)

Convenience function for returning a 1 dimensional ndarray of values from X, layers[k], or obs.

Made for convenience, not performance. Intentionally permissive about arguments, for easy iterative use.

layer : str | NoneOptional[str] (default: None)

What layer values should be returned from. If None, X is used.

Return type

ndarray

• A one dimensional nd array, with values for each obs in the same order

• as obs_names.
