zica

zica(activations, frames=None, baseline_frames=None)

Z-score ICA activations from repeated within-epoch baseline frames.

Parameters:

• activations (Any) – Components by concatenated samples matrix.

• frames (int | None) – Samples per epoch, or the full data length for continuous data.

• baseline_frames (Any) – Zero-based frame indices within every epoch. At least three baseline frames are required.

Returns:

Z-scored activations, baseline standard deviations, maximum absolute z-scores, original zero-based component indices, and zero-based peak sample indices, all ordered by descending peak magnitude.

Return type:

tuple[ndarray, ndarray, ndarray, ndarray, ndarray]
