neuromodes.basis.calc_norm_power

neuromodes.basis.calc_norm_power(beta: ArrayLike) → NDArray

Transform beta coefficients from a decomposition into normalised power.

Parameters

betaarray-like

The beta coefficients array of shape (n_modes,) or (n_modes, n_maps), where n_modes is the number of orthogonal vectors and n_maps is the number of brain maps.

Returns

numpy.ndarray

The normalized power array of shape (n_modes,) or (n_modes, n_maps), where each element represents the proportion of power contributed by the corresponding orthogonal vector to each brain map.
