posact

posact(data, weights, sphere=None)

Flip ICA components whose negative samples have the larger RMS.

Parameters:

• data (Any) – Channels by samples input data.

• weights (Any) – Components by sphered-channels ICA weights.

• sphere (Any | None) – Sphering matrix, or None for identity.

Returns:

Reoriented activations, inverse unmixing matrix, and weights. All three outputs describe the same sign convention.

Return type:

tuple[ndarray, ndarray, ndarray]
