Analysis: Averaged instantaneous spike frequency vs Train number

The instantaneous frequencies of action potentials occurring on the waveform selected by the "Spike W.F. #" are averaged for each spike train on that waveform, and the averages are displayed for each train. That is, for each spike on this waveform, the instantaneous frequency (inverse of the interval from the previous spike) is calculated. For each train, the mean frequency is then plotted on the graph at the position representing the train number.

The spike trains for this waveform must be properly set. Intervals are calculated and averaged only for spikes in the same spike train, and no frequency is measured for the first spike in each train.
