OculoPy: Python package for saccade detection

System requirements:

This code has been tested on Python 3. Required packages can be found in requirements.txt

Usage

Assuming horizonal eye trace is in eye_x and vertical eye_trace is in eye_y:

• Fs: sampling frequency
• eye_x_t: horizontal eye trace timestamps
• eye_y_t: vertical eye trace timestamps

from OculoPy import SaccadeDetector

new_session = SaccadeDetector(HE = eye_x, t_HE = eye_x_t, VE = eye_y, t_VE = eye_y_t, eye_fs = Fs)

new_session._calc_saccade_velocity()

new_session._detect_saccades()

After a successful run the indices for detected saccades can be accessed through following class variables:

• new_session.saccade_onsets: saccade onset indices

• new_session.saccade_offsets: saccade offset indices

• new_session.saccade_onset_times: saccade onset times

• new_session.saccade_offset_times: saccade offset times
