R, ripples; FR, fast ripples; SOZ, seizure onset zone; HFOs, high-frequency oscillations. For example, in patient 1: the number 6 under R of interictal means that these six channels were detected up-threshold ripples. In these six channels detected ripples, there are five in SOZ. This also applies to FR.
