roi_analysis_example

This MATLAB project generates a synthetic dataset of regions-of-interests (ROIs) and their functional activity. The goal is to analyze ROI shapes and activity between sessions using principal component analysis (PCA) and a dimensionality score.

MATLAB Script Details

The example scripts (main file and utils) are used to:

• Compute a PCA-based similarity metric for ROI shapes across days
• Match real and shuffled ROIs across 8 simulated days
• Estimate ROI functional dimensionality
• Plot the results

Requirements

MATLAB 2022b Signal Processing Toolbox
