Script 015 – Average all waveforms
This script adds up all the existing waveforms, divides the result by the number of waveforms and then places it into a new waveform while hiding all other waveforms onscreen. This is a useful tool for visualizing the average data over a period of time from either several people (for example mean GSR response of 10 participants to a stimulus such as a startling sound) or from several recording locations (for example the change in oxygenation across all channels in the prefrontal cortex just following stimulus presentation). To average only the visible channels, excluding hidden channels, see Script 016.
