Affects: automatic selection of single-unit spike data
This parameter is used only when automatically setting single-unit data, to further eliminate spikes not rejected by the basic threshold-hysteresis-discriminator spike detection algorithm.
The signal is scanned from the spike onset, through to its fall below the "Spike baseline". The time from onset to baseline crossing is taken to be the width of the spike.
If the calculated spike width is less than the "Min. spike width" or greater than the "Max. spike width", the spike is rejected.
If the hysteresis is positive (above the threshold), the program will search for negative going spikes. In this case, the concepts of "rise" and "fall" are reversed, so the spike ends when it rises above the baseline.
