imarin18 3 Posted Wednesday at 10:24 AM Dear @maple I suppose that you faced the situation possibly due to the following two reasons. 1: Your computer does not have enough specification to get the data at 120Hz sampling rate. A computer with better specification could enable it to sample at 120Hz. 2. If you look at only the initial samples (i.e. first 30 seconds after you start sampling), you will see lower sampling rate than 120Hz. The following article may be helpful for you to understand these points. https://doi.org/10.3389/fpsyt.2020.572938 Best regards, imarin18 Share this post Link to post Share on other sites
