    Morph maps can be generated with mne_make_morph_maps. If one isn't
    available, it will be generated automatically and saved to the
    ``subjects_dir/morph_maps`` directory.

    Parameters
    ----------
    subject_from : str
        Name of the original subject as named in the SUBJECTS_DIR.
    subject_to : str
        Name of the subject on which to morph as named in the SUBJECTS_DIR.
    subjects_dir : str
        Path to SUBJECTS_DIR is not set in the environment.
    xhemi : bool
        Morph across hemisphere. Currently only implemented for
        ``subject_to == subject_from``. See notes of
        :func:`mne.compute_source_morph`.
    %(verbose)s

    Returns
    -------
    left_map, right_map : ~scipy.sparse.csr_matrix
        The morph maps for the 2 hemispheres.

    Note that this is close, but not exactly like the C version.
    For example, parts are more accurate due to double precision,
    so expect some small morph-map differences!

    Note: This seems easily parallelizable, but the overhead
    of pickling all the data structures makes it less efficient
    than just running on a single core :(
