This repository contains Python scripts and utilities for analyzing eye movement data collected during Vestibular/Ocular Motor Screening (VOMS) in virtual reality (VR) environments. The analysis includes processing, visualization, and statistical analysis of saccades, smooth pursuits, VOR, and VOR cancellation.

• Saccade Analysis: Detect and analyze saccadic eye movements.
• Smooth Pursuits: Measure and analyze smooth pursuit gain.
• VOR Asymmetry: Calculate the Vestibulo-Ocular Reflex (VOR) asymmetry index.
• Statistical Analysis: Perform various statistical tests and linear regressions.
• Visualization: Generate 3D plots and animations to visualize eye movement data.

To run the scripts, ensure you have the following Python packages installed:

pip install numpy pandas matplotlib scipy seaborn scikit-learn colorama tqdm

1. Preprocessing:

   • Place your experimental CSV files in the appropriate directory.
   • Use the provided functions to extract and preprocess data.

2. Running the Analysis:

   • Modify the script parameters as necessary for your dataset.
   • Execute the script to perform the analysis.

python vr_voms_all_eye_analysis.py 

3. Visualization:
   • The script will generate various plots and animations to help visualize the results.
   • Output files can be saved in the desired format.

This is the main script for analyzing VOMS data. It includes several classes and functions:

• vrVomsSaccade: Class for processing and analyzing saccades.
• vrVomsSymptoms: Class for analyzing VOMS symptoms data.
• Utility functions for data extraction, filtering, and statistical analysis.

• vr_voms_utils.py: Contains utility functions such as find_files, az_el, detect_square_wave_periods, and more.
• vr_voms_symptoms.py: Handles symptom data specific to the VOMS protocol.
