To set up groups for the test:
1. Click Append, to add a row for a new group.
2. Enter a name for the group in the Name column.
3. To select a signal type for the group, right-click the cell in the Signal Type column and select
Free Run, Triggered or Averaged.
4. If you select the Triggered or Averaged signal type then right-click the cell in the Trigger (Stim)
column to select from a menu of the stimulators you set earlier.
5. Use the Stim Delay column to set the stimulation delay for Groups set up with Interleaved
timelines.
6. The Stim Delay button in the bottom right corner of the Groups tab is used to automatically
calculate the Stim Delay settings. The Stim Delay button does not work until after the Traces tab
has been set up.

the menu of timelines that you setup earlier in the Timelines tab.
9. The Capture column is used to set the threshold for capturing epochs of Free Run data. Right-
click a cell in the Capture column to select from the following options:
• Start Capturing/Recording: Use this setting to turn Capture on and off. You can also right-
click a particular waveform in a Waveform window to turn Capture on and off. When Capture
is turned on, there is a checkmark beside the capture value.
• Threshold: is the user-defined voltage value at which, if any data point exceeds this (and
does not exceed the “rejection threshold”) the data is “Captured” and displayed. Select to
enter the capture threshold in µV.
• Chime: is a user defined sound that will be played whenever a waveform is “Captured”.
Select a sound from the Chime menu to set a sound to play every time the waveform data
meets the Threshold.
