Step 1: Download Data

Download the required dataset from the following link:

Example HCP preprocessed data

Place the unzipped data/ folder next to the codes/ folder (i.e., as a sibling directory in the repository root) as shown above.

---

Step 2: Set Up Dependencies in MATLAB

Launch MATLAB and add all subdirectories inside the codes/ folder to the path:

addpath(genpath('codes'));

---

Step 3: Generate Results

To run the full pipeline and generate all result files, execute the following script in MATLAB:

run('codes/GenResults_All.m');

---

Step 4: Compute CMF and Generate Output Figures

To compute the cortical magnification factor (CMF) and other key visualizations:

run('codes/GenFigure_CMF_HCP.m');

This script will generate CMF maps and associated analysis results.

Notes

• The scripts are tested on MATLAB 2022b or later.
• If you encounter path or file errors, double-check that the folder layout matches the structure above.
