Analysis: W.F. averaging - spike occurrence in cycle


A number of bins are set up for each waveform in the "W.F. # list", corresponding to individual action potentials, or spike occurrences, in the cycles. For example, 10 bins represent the first 10 action potentials in each cycle. A sweep is triggered for each of these action potentials, and added into its corresponding bin. The window and delay are set as they are for spike triggered averages.

The "Spikes to skip" parameter can be set to indicate how many spikes to ignore at the beginning of each cycle. If it were set to, say, 5, then 10 bins would represent the sixth to the fifteenth actions potentials. If the "Reverse spike occurrences" option is then enabled, the 10 bins would represent the fifteen down to the sixth action potentials from the end of the cycle.
