This panel provides some basic control over which trials from the data file will be included in the analysis and how those trials will be grouped together for the purposes of averaging or display.

Variable Parameters

All parameters that vary across trials in the data file are listed under the title Variable Parameters.

Selected Values

For each variable parameter, all indicates that trials for all values of this parameter will be included in the analysis. To restrict the analysis to only those trials for which this parameter has a particular value, select the desired value.

Group by

These buttons allow the separation into groups (checked) or lumping together (unchecked) of trials that have different values of the particular parameter. The buttons are active only where Selected Values is set to all. If an active button is checked, then trials for this parameter will be separated into groups on the basis of the parameter values. If an active button is unchecked, then trials will be lumped together across all values for the parameter.
