The export single target frequency distribution commands are used to export a frequency distribution of the single targets in selected analysis domains by their target strength.
The export file contains a column for each single target frequency distribution analysis variables and a column for each target strength bin. Each row in the file contain the analysis results for a single domain, i.e. the value for each single target frequency distribution analysis variable and the number of targets or the mean TS value of targets in each bin.
To export the frequency distribution for a selection or a single region, see Exporting data.
You set the range of TS values that will be included in the analysis and the number of bins into which this range is divided using the settings in the Frequency Distribution section on the Analysis page of the Variable Properties dialog box.
Hint: You can graph the frequency distribution prior to exporting to visualize the binning and target information that will be exported.
You can export either the number of targets in a bin and/or the TS mean of targets in a bin.
You select which values to export on the Export page of the EV File Properties dialog box).
|
To export... |
In the Export these analysis variables box, select... |
|
the number of targets in each bin |
Bin_count |
|
the mean TS value of targets in each bin |
Bin_TS_mean |
If you select one option, the exported file will contain a single line for each domain that is analyzed. If you select both options, the exported file will contain two rows (one after the other) for each domain that is analyzed.
The single targets frequency distribution by regions export command is used to export a frequency distribution of single targets, by target strength, for analysis regions in an echogram. The data are exported to a single .csv file.
To export single targets frequency distribution by regions:
Bring the single target echogram into focus.
On the Echogram menu, point to Export, point to Analysis by Regions, and then click Frequency Distribution.
Notes:
The column heading for each TS bin column represents the mid point of the targets strength values included in the bin, e.g. a bin that includes targets with target strength between -50 dB and -60 dB, would have '-55' dB as the column heading.
The regions for which a frequency distribution will be exported is affected by exclusion lines selected on the Analysis page of the Variable Properties dialog box.
Regions that do not contain any targets will not be analyzed.
All settings in the Variable Properties dialog box except those on the Display page are applied to calculations.
This command will only be available if at least one analysis region has been defined on the selected echogram.
You can only export single target frequency distribution if you have purchased an Analysis export module license.
The single targets frequency distribution by cells export command is used to export a frequency distribution of single targets, by target strength, for cells on an echogram.
You must select an export format on the Export page of the EV File Properties dialog box before using this command. You can select:
spreadsheet format: to export to a single .csv file for analysis using a spreadsheet application.
database format: to export data to multiple .csv files for analysis using a database application.
To export a single targets frequency distribution by cells:
Bring the single target echogram into focus.
On the Echogram menu, point to Export, point to Analysis by Cells, and then click Frequency Distribution.
Notes:
The column heading for each bin represents the mid point of the TS values of the bin, e.g. a bin that includes targets with TS values between -50 dB and -60 dB, would have '-55' dB as the column heading.
The cells for which a frequency distribution will be exported is affected by the exclusion lines selected on the Analysis page of the Variable Properties dialog box.
The cells for which a frequency distribution will be exported is not affected by output empty cells option on the Export page of the EV File Properties dialog box, i.e. empty cells will not be analyzed or included in the export.
This command will only be available if you have defined a time/distance by depth grid on the Grid page of the Variable Properties dialog box.
All settings in the Variable Properties dialog box except those on the Display page are applied to calculations.
This command will not be available if a grid is not defined in your echogram.
You can only export single target frequency distribution if you have purchased an Analysis export module license.
The single targets frequency distribution by regions by cells export command is used to export a single targets frequency distribution, by target strength, for region-cell intersections on an echogram.
You must select an export format on the Export page of the EV File Properties dialog box before using this command. You can select:
spreadsheet format: to export to a single .csv file for analysis using a spreadsheet application.
database format: to export data to multiple .csv files for analysis using a database application.
To export a single targets frequency distribution by regions by cells:
Bring the single target echogram into focus.
On the Echogram menu, point to Export, point to Analysis by Regions by Cells, and then click Frequency Distribution.
Notes:
The column heading for each bin represents the mid point of the TS values of the bin, e.g. a bin that includes targets with TS values between -50 dB and -60 dB, would have '-55' dB as the column heading.
The region-cell intersections for which a frequency distribution will be exported is affected by the exclusion lines selected on the Analysis page of the Variable Properties dialog box.
The region-cell intersections for which a frequency distribution will be exported is not affected the output empty cells option on the Export page of the EV File Properties dialog box.
This command will only be available if you have defined a time/distance by depth grid on the Grid page of the Variable Properties dialog box.
All settings in the Variable Properties dialog box except those on the Display page are applied to calculations.
You can only export single target frequency distribution if you have purchased an Analysis export module license.
