Regions page
The Regions page of the Variable Properties dialog box is used to select which region classes are visible for a particular variable and, where applicable, how regions are created during live viewing.
Visible region classes
All region classes in the EV file are listed. Only regions belonging to the selected region classes are displayed for this variable. Region visibility on this page does not affect processing, integration, or other analysis results.
Notes:
- The region visibility state for upstream variables is unaffected by the visibility specified by the current variable.
- Use Show all or Hide all to select or clear region class visibility.
- On multibeam echograms, 3D regions are displayed as region-ping intersections.
Detection
The preferred detection configuration setting displays the detection configuration selected for this variable. The available setting and configurations depend on the variable’s data type, as shown below.
A configuration selected here overrides the preferred detection configuration specified on the Region Detection page of the EV File Properties dialog box.
Variables with this data type... |
can use ... |
to detect ... |
Single target |
Fish track detection configurations | fish track regions |
Single beam and wideband: Sv, Power dB, TS, Linear, Unspecified dB |

Multibeam school detection configurations | 3D school regions |
Click the Edit Region Detection Configurations... button to use the Region Detection page of the EV File Properties dialog box to create, view, or manage detection configurations.
Live viewing
Configure school detection while live viewing here (for supported data formats).

Description |
|
Automatically detect schools during live viewing |
If selected, Echoview automatically detects 2D schools whenever new data arrives during live viewing. |
|
Assign class |
Specify the region class to be assigned to detected schools. |
|
Edit |
Click to display the Classes page of the EV File Properties dialog box. |
|
Run classification after detection |
Select this setting to classify detected school regions using the specified rules. Refer to Classify regions for more information. |
Note: The rate at which data arrives can significantly influence performance because schools are detected again whenever new data arrives. See Using Echolog 500 or Using Echolog 60 for information about adjusting this rate.
