Analysis: Averaged trace spike count vs step cycle


The average number of spikes found for each frame, on the trace selected by the "Spike trace #", are displayed with respect to cycles on the waveform selected by the "Cycle W.F. #". That is, the cycles are divided into a number of bins, and for each cycle on the latter waveform, the corresponding frames are examined. For each of these frames, the selected trace is searched for spikes, and the number of spikes found is added to the bin at the position in the cycle where the frame was triggered. All data are added into the bins in this way to obtain an average curve which is displayed.

The spike measurement is controlled by the parameters "Trace spike threshold", "Trace spike hysteresis", and "Trace spike discr.". The "Trace spike delay" is simply an offset from the start of the frame's window where the search for spikes is to begin; if set, spikes before this delay are ignored. The data for all cycles in the range to be analysed are overlaid on the graph. Deleted frames, and frames whose tag values are not in the "Tag list" are excluded.
