Field Contents

Name * Label of the custom interest area set

IA Count Total number of interest areas defined in the trial

IsCustom Whether the current set of interest areas is user-defined (true) or an interest area template (false)

Image Name Mapping If the "Auto Select IAS for Trial" property in the

“Output/Analysis” preference settings is true, the value in this field will be used to associate the IAS to trials automatically

(see section 5.8.8 “Automatic Trial Image-Interest Area Set

Association” for details).

4.1.1.5 Custom Interest Area Set/Empty Interest Area Set

For each trial, the tree view also shows whether or not a custom interest area set has been defined for the trial. If there is no interest area set, the node will be “Empty Interest

Area Set”. The property panel lists the same elements as the interest area templates, except that the IsCustom field is “true” for the custom interest area set.

4.1.2 Preferences Tab

The preferences tab (Figure 4-2, right panel) provides access to all the elements of the data viewer that can be configured by the user. These include everything from the default colors used for displaying events, to the elements of an EDF file to load. These elements are broken down into the following five categories: General Preferences, Data Loading

Preferences, Output/Analysis Preferences, Data Filters Preferences, General Trial View

Preferences, Spatial Overlay View Settings, Temporal Graph View Settings, and

Animation Playback Settings.

4.2 Trial View Window

The Trial View window displays the data of a selected trial in a Spatial Overlay Mode, a

Temporal Graph Mode, or an Animation Playback Mode. Selecting a trial in the Data

Inspector tree view shows the trial’s data in a Trial View Window. The user can have several Trial View Windows open at one time by right clicking on a trial in the Inspector window and selecting “New Window” in the popup menu.

4.2.1 Selecting Data Elements to Display

At anytime event visibility can be toggled on/off within the Trial View Window. For example the button in the Application Desktop toggles the visibility of Fixation

Events.
