Converting EDF to CSV

Converting EDF to CSV#

📌 How to Use export()#

The export function takes an EDF file as input and converts it into CSV files.

✅ Basic Usage (File in the Same Directory)#

If your .EDF file is in the same directory as your script, simply run:

import etformat as et

# Convert 'test.EDF' (must be in the same folder as your script)
et.export("test.EDF")

  • The CSV files will be saved in the same folder as test.EDF.

📂 Specifying a File Path#

If your .EDF file is located in another folder, provide the full or relative path:

# Convert an EDF file located in another folder
et.export("/path/to/your/file.EDF")

For example:

et.export("C:/Users/YourName/Documents/myfile.EDF")

or on macOS/Linux:

et.export("~/Documents/myfile.EDF")

🎯 What Happens After Running export()?#

  • The EDF file is processed and converted.

  • Two CSV files are created in the same directory as the EDF file:

    1. filename_events.csv → Contains event-related data.

    2. filename_samples.csv → Contains sampled eye-tracking data.

Example Output:#

If you run:

et.export("C:/data/test.EDF")

You will get:

C:/data/test_events.csv
C:/data/test_samples.csv

⚠️ Common Errors & Solutions#

❌ File Not Found#

Error Message:

FileNotFoundError: Error: The file 'test.EDF' does not exist. Check the path and try again.

Solution:

  • Make sure the file exists at the specified location.

  • Use an absolute path if needed.

  • Double-check spelling and file extensions.

❌ Permission Error#

Solution:

  • Ensure you have read/write access to the folder where the file is stored.

  • Try running the script as an administrator (Windows) or using sudo (Mac/Linux).
