Analysis export changes under Echoview 12
Improvements and changes for analysis export issues and outputs for new EV files created under Echoview 12 and on.
Behavior under Echoview 12 |
Previous issue |
|
Improvement of the handling of fish track regions that cross data files followed by the removal of a data file. The end of the region uses the ping time to terminate as if the region extends on. |
Such fish track regions clamped the end of the region to the last ping and terminated to a vertical point. |
Density_weight, Density_number When intervals are composed of all bad data or all excluded samples, and the Density_weight and Density_number can't be calculated, the output result is zero. |
An incorrect value was exported. |
|
Analysis by Region Classes by Cells, To ICES CSV under a line-reference grid exports results as expected. |
The export included duplicated rows with values set to zero. |
|
Analysis domains filled with no data output a value for Range_mean or Depth_mean. Analysis domains with excluded samples (via exclusion lines) return zero for Range_mean and Depth_mean; this behavior is unchanged. |
An incorrect value of zero was exported for analysis domains filled with no data. |
Fish tracks by cells (database) export Targets from invalid fish tracks are not list in the targets file. |
Targets from invalid fish tracks were listed in the targets file. |
|
3D_school_volume calculates as expected. |
3D_school_volume was reporting zero in cases where it could be calculated. |
Column changes for analysis export files
Changes for the following analysis exports under new EV files. Pre-existing EV files are unaffected by these new behaviors.
- Use the Export page of the EV File Properties dialog box to specify the Output format (Database/Spreadsheet).
- About analysis variables lists specifiable and automatically exported variables.
