EyeLinkOgamaConnector

EyeLinkOgamaConnector is a Python script, which reads converted log files from EyeLink to create a .csv compatible with Ogama.

Disclaimer 1: The code is very specific to our use case and may need substantial changes to work with other setups. Disclaimer 2: I am not a Python programmer. I'm always grateful for feedback on how to improve my code.

Setup

The project should run in any Python 3.6 environment. It was developed with the PyCharms IDE.

Sample data for participant p01 is provided, you should be able to run the script without any changes for this demo case.

Conversion from EyeLink to Ogama

Required File Names

• All files are in the same directory
• EyeLink eye-tracking log: *participant_id*.asc
• [Optional] Response: *participant_id*_response.log
• [Optional] Physio: *participant_id*_physio.log

Work Flow

Before starting the Python script, prepare the data.

• Get .edf log file from EyeLink
• Convert .edf file to an ASCII-file .asc with EyeLink's edf2asc-Tool.
• Move .asc file to the project's /input folder
• [Optional] Add physio and response log files according to the conventions above

Next, use EyeLinkOgamaConnector:

• Check and make necessary configuration adjustments to OgamaConnector.py
• Run OgamaConnector.py

Possible usages after everything is done:

• Import to Ogama with the output .csv file
• Use analysis scripts/pipeline directly on the .csv file (see related repositories)
