Event classes (blinks, fixations, saccades, events)

class pyneon.events.NeonEV(file)

Bases: NeonTabular

Base for Neon event data (blinks, fixations, saccades, “events” messages).

property start_ts: ndarray

Start timestamps of events in nanoseconds..

property end_ts: ndarray

End timestamps of events in nanoseconds.

property durations: ndarray

Duration of events in milliseconds.

property id: ndarray

Event ID.

crop(tmin: Number | None = None, tmax: Number | None = None, by: Literal['timestamp', 'row'] = 'timestamp', inplace: bool = False) → NeonEV | None

Crop data to a specific time range based on timestamps or row numbers.

Parameters:

• tmin (number, optional) – Start timestamp/row to crop the data to. If None, the minimum timestamp/row in the data is used. Defaults to None.

• tmax (number, optional) – End timestamp/row to crop the data to. If None, the maximum timestamp/row in the data is used. Defaults to None.

• by ("timestamp" or "row", optional) – Whether tmin and tmax are UTC timestamps in nanoseconds or row numbers of the stream data. Defaults to “timestamp”.

• inplace (bool, optional) – Whether to replace the data in the object with the cropped data. Defaults to False.

Returns:

Cropped stream if inplace=False, otherwise None.

Return type:

NeonEV or None

restrict(other: NeonStream) → NeonEV

Restrict events to a time range defined by another stream.

Parameters:

other (NeonStream) – Stream to restrict to.

Returns:

Restricted event data.

Return type:

NeonEV
