I am interested in doing some analyses on the PAC maps from some sensor data. When run the phase-amplitude coupling process, the corrresponding map is stored in the 4D sPAC.DirectPAC matrix, but when I try to average this across trials, I only get the 1D TF variable. I was wondering if there is an easy way to extract the PAC maps and create a user matrix? Is there a process that exists that handles this, or will I need to come up with something? Also, if I decide to improvise, what are the necessary attributes of a bst user matrix?
