Pupillometry App

A scientific utility designed for preprocessing, visualizing, and analyzing raw pupillometry data, configured by default for data exported from the iMotions platform.

The app is purpose-built to meet the specific needs of researchers and was created as a graduation project.

Documentation

Find documentation in both English and Polish in the /docs folder.

Note: Unfortunately, GitHub may corrupt PNG files, causing image-related issues.

Key Features

• Preprocessing: Efficiently prepares raw pupillometry data.
• Visualization: Provides visualizations for insightful analysis.
• Analysis: Conduct in-depth analysis tailored to researchers' needs.

Features

Data Processing:

• Remove artifacts from data.
• Calculate various metrics.

Visualization:

• Display data graphically.
• Save charts as PNG.

Data Analysis:

• Breakdown data by task/scene/segment.
• Analyze left and right eye metrics.

Study Management:

• Create/Delete Studies and Groups.
• Add/Delete Respondents to Groups.

Export and Configuration:

• Export metrics to Excel files.
• Configure custom settings.

Advanced Options:

• Test preprocessing on a single respondent.
• Resample and smooth data.
• Calculate baseline.

Enhanced Metrics:

• Extra metrics (Z-score, Relative, ERPD/PCPD).
• Include a legend in export files.
• Manually mark segment validity.

Selective Features:

• Eye selection.
• Divide trial by time windows.
• Create task groups when exporting data.
• Filter metrics in group view by selected segments.

Recommended Config

The recommended configuration provides optimal settings for various aspects of data processing, visualization, and analysis. Customize as needed for your specific use case.

Getting Started

1. Go to releases page
2. Download Pupillometry-1.1.4-mac.zip or Pupillometry-1.1.4-win.zip depending on your operation system.
3. Unzip and use
4. In case of any issues read the /docs or ask me

Note: App build was tested only on windows 10. For windows, you may see a warning about preventing an unrecognizable application from running. This is due to the lack of certification, which requires a fee. In such a situation, you should ignore and run anyway.

OR run in development mode:

1. git clone [url]
2. install node.js
3. npm install --global yarn
4. yarn install
5. yarn start
