abspeak

abspeak(data, frames_per_epoch=None)

Return absolute peaks, zero-based frames, and signs for each epoch.

NaNs are ignored when finite or infinite observations exist. An all-NaN channel/epoch returns NaN amplitude, frame -1, and sign NaN. Tied peaks use the last frame, matching EEGLAB’s stable-sort behavior.

Parameters:

• data (Any)

• frames_per_epoch (int | None)

Return type:

tuple[ndarray, ndarray, ndarray]
