mne.event.define_target_events¶

mne.event.define_target_events(events, reference_id, target_id, sfreq, tmin, tmax, new_id=None, fill_na=None)[source]¶

Define new events by co-occurrence of existing events.

This function can be used to evaluate events depending on the temporal lag to another event. For example, this can be used to analyze evoked responses which were followed by a button press within a defined time window.

Parameters:

events : ndarray Array as returned by mne.find_events. reference_id : int The reference event. The event defining the epoch of interest. target_id : int The target event. The event co-occurring in within a certain time window around the reference event. sfreq : float The sampling frequency of the data. tmin : float The lower limit in seconds from the target event. tmax : float The upper limit border in seconds from the target event. new_id : int new_id for the new event fill_na : int | None Fill event to be inserted if target is not available within the time window specified. If None, the ‘null’ events will be dropped.

Returns:

new_events : ndarray The new defined events lag : ndarray time lag between reference and target in milliseconds.
