Alternatively, open the <code>src/MFBrain.nb.html</code> file to see the results without having to run the code. The notebook starts from the raw behavioral data, but not from the raw EEG data: it uses text files in <code>data/EEG/statistics</code> that were written out from MATLAB.</p> </li> <li> <p><strong>To reproduce the figures in the paper</strong>: Run the <code>/src/MFBrain_master_reproduce.m</code> script in MATLAB, which loads the provided group EEG data and statistics text files.</p> </li> <li> <p><strong>To recompute the ERP and EEG time-frequency measures</strong>: Run the <code>/src/MFBrain_master_recompute.m</code> script in MATLAB, which loads the preprocessed EEG data.</p> </li> </ul> <p>Note that unfortunately we cannot provide a way to reproduce the preprocessed data from the raw data as the preprocessing for this project was not fully scripted out.</p>
