FAQ

What are the use cases for "volts" versus "RMS Multiple" values for the threshold or display units?

The properties {waveformAmpUnits,thresholdType} can each be 'volts' or 'rmsMultiple'.

For spike-triggered waveform mode, all of the 4 possible combinations have distinct uses and characteristics:

Case 1: {'volts','volts'}
Use: Signal (peak heights) & noise levels (RMS) are consistent across channels

Case 2: {'volts', 'rmsMultiple'}
Use: Noise varies significantly across channels
Characteristic: Threshold line differs per channel

Case 3: ('rmsMultiple', 'volts')
Use: Signal (peak heights) varies significantly across channels
Characteristic: Threshold line differs per channel

Case 4: ('rmsMultiple', 'rmsMultiple')
Use: Noise & signal both vary significantly across channels

For stim-triggered waveform mode: the threshold is irrelevant. For raster mode, the display units (waveformAmpUnits) are irrelevant
