Transition from Echoview 4

Echoview 5 and higher introduces:

  1. Major changes to the reading and modification of acoustic variable calibration settings.
    • Echoview reads calibration settings from data files, and can also determine where changes in calibration settings occur.
    • Modifications to calibration settings are made in one place - the ECS file.
    • Such modifications can be specified at three levels: Fileset, SourceCal and LocalCal. Fileset and SourceCal settings apply seamlessly to multiple variables. LocalCal settings are variable-specific.
    • An ECS file may be used by many EV files and is copied to EV file templates.
    • Use of default calibration settings is flagged.
    • Virtual variable transducer and calibration inheritance is from the first operand.
  2. Multi-thread processing for data reading and virtual variable chains.
  3. Modern document features for the Echoview application, the Variable Properties dialog box and the EV File Properties dialog box.

This page details some of the changes and their implications for existing EV files. Some existing EV files will require editing to make them work properly in Echoview 5 and higher.

Calibration upgrade considerations for Echoview 4 EV files

Before Echoview 5:

  • Only, Simrad Ex60 data could take calibration values using the From first ping feature on the Calibration page of the Variable Properties dialog box.
  • Onscreen editing was used to modify calibration settings. Calibration setting modification was per-variable and independent. The EV file recorded the calibration settings used for each variable.
  • Where calibration values were required for calculation but were unavailable, a default value was used.

Read calibration data from file.

Calculations use settings read from the data file, user specified settings and default settings

  • Calibration settings on the Calibration page of the Variable Properties dialog box are different from those used in Echoview 4.90.
  • Calibration 2 page of the Variable Properties dialog box is absent - this is a deprecated page.
  • New Geometry section on Calibration page.
  • New Calibration section on Calibration page.
  • Calibration section displays SourceCal, LocalCal and Used by pings.
  • Message box Default calibration setting messages.
  • Single target echograms look odd - the Thickness factor has changed.

Calibration page settings

  1. Note the settings used in Echoview 4.90.
  2. Compare with the historical calibration settings that Echoview can extract.
    1. Help menu > Calibration Information
    2. Under Settings, drag to select text.
    3. Shortcut menu > Copy
    4. Paste to a file (in Notepad).
  3. Calibration page - the Transducer list allows the selection of a transducer.
  4. Calibration page - SourceCal displays the Calibration Source for the variable.
  5. Calibration page - the LocalCal list allows the selection of LocalCal settings from an ECS file.
  6. Calibration page - the Used by pings section displays the calibration settings used by the variable.
  7. To modify the calibration settings, create a new ECS file using New in the Calibration section of the Filesets window.
  8. Edit the ECS file (in Notepad) with the correct calibration settings.
  9. Save the ECS file.

For detailed instructions refer to:

Single target echograms

The Echoview 5 calibration and Properties dialog box changes may affect the display of single target echograms by changing the Thickness factor on the Data page of the Variable Properties dialog box.

You can modify the Thickness source and the Thickness factor to more suitable values.

Virtual variable transducer and calibration inheritance is from the first operand.
  • Complex calibration inheritance is not available.
  • Transducer for complex virtual variable chains may change.
  1. Virtual variable calibration settings are inherited from the first operand.
  2. The Transducer for a virtual chain is the transducer of the first operand (and raw variable) at the start of the virtual chain.
Change calibration settings with an ECS file
  • Can't change the onscreen setting with the mouse or keyboard.
  1. Create a new ECS file using New in the Calibration section of the Filesets window.
  2. Edit the ECS file (in Notepad) with the correct calibration settings.
  3. Save the ECS file.

For detailed instructions refer to:

New Echoview 5.0 COM EvCalibration

 

  • Echoview 4.90 EvCalibration is not supported. Scripts using 4.90 EvCalibration methods and properties and EvVariables.Collection.UseCalibrationInheritance are broken.
Refer to Transition for calibration scripting

Multi-threaded data reading
  • No increase in processing time.
  • The multi-threading feature works under one or more computer cores. Multi-threading increases Echoview's responsiveness to user actions. Multi-threading and multiple cores offer faster calculation times.
33+ Multi-threaded operators
  • No increase in processing time.

The Echoview workspace extends outside of the Echoview window.

New docking model enables echogram and other windows to dock to each other.

  • Windows tabs toolbar absent; it is deprecated.
  • Windows functions toolbar; it is deprecated.
  • Echograms or dialog boxes can be dragged to the desktop outside of the Echoview window.
  1. Echograms, Scenes, Dataflow, Fileset Windows dock when opened. Drag to dock elsewhere or float or tab; anywhere on the desktop.
  2. Many dialog boxes float, some dialog boxes dock to the Echoview window.
  3. Docked items occupy a panel. Panels can contain panes.
  4. Use Window menu > Arrange All, to optimize the panels and panes within the Echoview window.
  5. Use Window menu > Arrange Panes, to optimize the panes in a panel.

For more details refer to About the Dataflow window.

Default settings for new EV files.

  • Whole excluded or no-data pings removed from ping count is selected on the Analysis page of the Variable Properties dialog box. In general, this setting would be correct to use. There is a case where this state may not be correct.
    For more information refer to About samples and echo integration:Integration calculations - Note.
  • Weighting/Interpolation range selected (as a default) under the Mean resampling operation. This setting is necessary when the data range is shifted from its original value. Pre-Echoview 5.0 EV files are unaffected by this change.
  • The default background color of new scenes is light gray.
  • To facilitate single target detection, the single target detection operator (single, split, dual) default value for Minimum normalized pulse length is now 0.7.

These changes affect new EV files and new virtual variables. Pre-Echoview 5 EV files with existing virtual variables are unaffected.

However, please the consider the reasons for these defaults and whether they would benefit your processing and analysis.
