Error in Phase amplitude coupling

tPAC.pdf (357.4 KB)

Dear Francois,

I have done it according to the pipeline mentioned in the tutorial (page 2) and comodulogram can be generated. However, I was wondering why the tPAC comodulogram cannot be generated with the settings (low freq. 4-8; high freq. 30-90) shown in page 1. Here I would like to specifically see theta gamma coupling for my data.
What is the rationale behind choosing those broader frequency ranges (low freq. 3-15Hz; high freq 20-200Hz)?

Thanking you
Ashika
