The current waveform is displayed as a thick, black line. Threshold waveform is specified by a dashed line. If a negativity or positivity is selected, it will be indicated by a white symbol. Negativities are indicated by triangles, positivities as squares. Red is P1/N1, yellow is P2/N2, green is P3/N3, light blue is P4/N4, and dark blue is P5/N5.
The following keybindings are used when processing a waveform series:
Waveforms
•Up/Down arrows – Select previous/next waveform in the series
•P – Toggles waveform polarity. Do this before any other data processing.
•N – Toggles normalized view of waveform.
•+/- keys – Increases/decreases scaling factor of waveform.
Peaks / Notches
•Right/Left arrows – Move a toggled peak left or right along the waveform. Movement of the peak will "snap" to estimated peaks in the waveform. To adjust the peak in fine increments, hold down the shift key simultaneously.
•Number keys 1-5 – Select the corresponding peak on the current waveform. To select N1-5, hold down shift while pressing the corresponding number.
•I – Estimates N1-5 for all waveforms. If N1-5 is already estimated, recomputes the estimate.
•U – Updates guess for corresponding P or N of successive waveforms based on position of currently toggled P or N.
Threshold
•Return – Set threshold to current waveform.
•T – Estimates threshold using the correlation coefficients between responses to adjacent levels.
•W – Toggles display of threshold estimation details.
Analysis
•L - Toggles display of input-output function
•X – Clears analysis, restarts with initial peak guess.
•R - Restores last-saved analysis
Saving
•S – Saves amplitude and latency of peaks.
•E - Export filtered waveforms
The appropriate keys will repeat if you hold down the key, which may be useful when navigating through the waveforms or adjusting the location of a peak.
