[Eeglablist] Online workshop PREPROCESSING MUSE DATA IN EEGLAB part IV

[Iversen, John]

Hi Floris,

Sounds interesting. What kind of questions are you asking about music and the brain?

Regarding the figure there are two answers--for the statistical comparison, you would set that up in the GUI (e.g. at 4:21) with the STATS button.

For the plot, that does look nice. Arno can weigh in on how he prepared it, but here's a basic example of how you can plot a transparent patch on top of an axis, which you could generalize to frequency bands or significance ranges or whatever...

figure
axis([0 1 0 1]) %fix axis limits so a patch stretching outside of the axis does not change its limits
patch([0.2 0.5 0.5 0.2 0.2],[-.05 -.05 1.05 1.05 -.05],[1 0 0], 'facealpha', 0.2,'edgecolor','none','clipping','off')

I have a collection of utility functions on github, and one of them does just this: https://urldefense.com/v3/__https://github.com/jiversen/ji_utils/blob/main/patchx.m__;!!Mih3wA!HzCqgNn2kl6RQsviTXJNNUNGMV0UaFWyEmRoL02d14s8m_zW7UFYBr47YgZ7GczsGyxU6GCSyxXeHqPLYUFpivj7$ 

Best,

John

Dear all,





I am a pre-university college student at the Rijnlands Lyceum Wassenaar in the Netherlands. I am writing a paper on how the brain processes music. My research involves the use of the MUSE EEG headband and processing the data in EEGLAB. The online workshops on EEGLAB.org<https://urldefense.com/v3/__http://EEGLAB.org__;!!Mih3wA!HzCqgNn2kl6RQsviTXJNNUNGMV0UaFWyEmRoL02d14s8m_zW7UFYBr47YgZ7GczsGyxU6GCSyxXeHqPLYQI9or3S$ > have been most helpful. I have a question about Part IV of Preprocessing MUSE Data in EEGLAB, https://urldefense.com/v3/__https://www.youtube.com/watch?v=y8jK-bW1U3A__;!!Mih3wA!FoZrauLr5tdyIGrPQj6wwjbqiVLLnz9zZXVLLyxWuvQqC5Jexrvki1Ey55LBJrhxrvNFg2ax4CuZe15qPjgard0L$ . At the 4:30 mark a graph is shown with the different frequency ranges plotted for the AF7 electrode. I would like to reproduce this plot, but so far I have not succeeded. Could anyone give me a hint on how to reproduce this graph with the statistical significant differences displayed in the different frequency bands? Thank you!


Kind regards,
