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.
