FAQ: How can I group / separate my trials?
#1
Trials can be grouped or regrouped using any combination of the Trial Variables available in the current Data Viewer Viewing Session. This can be done by going to the Edit menu -> "Trial Grouping ..." in the main Data Viewer toolbar and selecting the relevant variables that group those trials together.

   

Note that the order in which the trials appear on the right column will affect the trial grouping in the Inspector window as they are grouped hierarchically.
