Hello,

I was looking through the tutorial on noise covariance and came across this option for calculating the matrix for epilepsy data.

Option #1a Compute the noise covariance statistics from blocks of recordings away from the peak of any identified interictal spike, and keep only the diagonal (the variance of the sensors).

I was wondering if by 'keep only the diagonal' it was meant to export the files to matlab and zero all other values? If so, would you zero the non-diagonal values from the NoiseCov variable as well as the FourthMoment?

I apologize if this has gone under the wrong Topic
