Analysis: Averaged W.F. amplitude vs step cycle

Home › Software › Analysis Help › Methods › Averaged W.F. amplitude vs step cycle


The waveform selected by the "Amplitude W.F. #" is averaged and displayed with respect to cycles on the waveform selected by the "Cycle W.F. #". That is, the cycles are evenly divided into a number of bins, and for each cycle on the latter waveform, the corresponding segment of the former waveform is split up and the parts are added into their respective bins. An average curve is then calculated and displayed with one point for each bin.

If the cycle related parameters for the displayed waveform have been properly set, statistics will be given for activity on this waveform, relative to the above cycles. The parameters "Min W.F. amplitude" and "Max W.F. amplitude" can restrict the voltage levels allowed in the analysis to a smaller range.

The "locomotor drive potential" reported at the top of this graph is simply the difference between the minimum and the maximum averages calculated.
