📌 Introduction to etformat#
etformat is a Python package designed for processing and analyzing eye-tracking data from EDF (Eye Data Format) files. It provides tools to convert, extract, visualize, and analyze gaze data with ease.
🔹 Key Features#
✔ Convert EDF to CSV for easy access (export())
✔ Extract metadata like sampling rate & screen size (edfinfo())
✔ Analyze trials for fixations, saccades & blinks (describe())
✔ Visualize gaze paths (plot_gaze())
✔ Plot saccades with movement directions (plot_saccades())
✔ Extract and validate calibration data (calibration())
🚀 Quick Example#
import etformat as et
# Convert EDF file to CSV
et.export("test.EDF")
# Extract EDF metadata
et.edfinfo("test.EDF")
# Analyze trials
et.describe("test.EDF")
# Plot gaze for trial 3
et.plot_gaze(samples, trial_number=3)
# Plot saccades for trial 3
et.plot_saccades(events, trial_number=3)
# Extract calibration details
et.calibration("test.EDF")
#Clean EDF fiel and Preprocess
et.clean('file')
#Average Saccade Report
et.saccade_amplitude_average(events)
#Recording report
et.report(events)
✅ Easy to use, powerful, and built for eye-tracking research! 🚀
