About the Filesets window

The Filesets window (F10) is used to manage filesets, which consist of data files, raw variables and Echoview Calibration Supplement files (ECS files).

To display the Filesets window:

- OR -

Fileset pages

Each fileset that has been created within an EV file is displayed on a separate page in the Filesets window.

To display a fileset, click a Fileset page.

Each fileset is made up of the following sections:

Data files section

The Data files section of the Filesets window displays the data files that have been added to the selected fileset. A clock-circle next to the data file name shows the data file is being loaded.

Click Add to add a new data file. Use the Files format type list to concentrate on specific file types. You can also add data files to a fileset by using a drag and drop from Windows Explorer onto the Echoview window.

Click Remove or use the Delete key to remove selected data file(s) from the fileset.

Click Information to open the Data File Information dialog box.

Click the Folder icon to Show/Hide folder paths.

The Fileset properties icon opens the Fileset Properties dialog box where you can edit the fileset name, specify a method to derive raw variables, manage Dataflow window transducer creation and specify a time offset.

Select data files with the mouse and the actions on the right-click Shortcut menu to Copy data file paths to the clipboard to paste into text editors or paste the data file into a Window folder. Select the file(s) to copy and press CTRL+C. Shortcut menu, Show in File Explorer displays the data file in a Windows Explorer window.

If data files are unfound, click the first unfound file name and on the Shortcut menu, select Browse for file.... This will search for the first unfound file. Locating the first file will trigger subsequent unfound files to be found and loaded.

When Echoview initially reads the data file and it identifies problems in the data:

The data files are listed with the following properties:

Column

Description

Name

The name of the data file.

Folder

The folder in which Echoview expects to find the data file. UNC names are valid. If the Ignore data-file paths option is selected on the EV File page of the EV File Properties dialog box then this folder is ignored and the folder in which the EV file is found is used instead.

Note: Echoview attempts to use the EV file UNC path if it is available, to resolve relative file paths to data files, ESC files and other files. But be aware that changes to UNC paths (e.g. users adding, removing or renaming shared directories) could result in Echoview being unable to resolve the relative paths in some cases.

Start date/time

The date and time of the first ping in the data file.

Note: Set to "not yet determined" until you display an echogram of a variable derived from the data file, display information about the data file, or create a virtual variable that references the data file. 

End date/time

The date and time of the last ping in the data file.

Note: Set to "not yet determined" until you display an echogram of a variable derived from the data file, display information about the data file, or create a virtual variable that references the data file.

Calibration section

The Calibration section of the Filesets window displays the Echoview Calibration Supplement file (ECS file) that is associated with the data files in the fileset. An ECS file contains user-specified calibration settings that are applied to the data.

Click the Add file button to add an existing ECS file.

Click the New button to create new ECS file and add it to the fileset. The ECS file opens in the Notepad application and displays initial comments and file syntax. You may be able to Copy-Paste calibration names and values from the Calibration page of the Variable Properties dialog box or the Calibration Information dialog box. Refer to Calibration setting names and Syntax and grammar rules for the ECS file.

Click the Edit button to edit an added ECS file.

Click the Remove icon to remove the ECS file from the fileset.

Notes:

Raw variables section

The Raw variables section of the Filesets window displays the raw variables that Echoview has derived from the data file(s) in the Data Files section. Each variable is assigned a unique name to identify it meaningfully in Echoview (important in the use of templates). The number of measurements (pings, GPS fixes, vessel log points, etc. as appropriate to the variable class) is displayed after the variable name. The (x | y) name notation indicates x read of y measurements in the file. After an Echoview calculation, the notation may change to (F, y). F is frequency (if it is available).

The checkbox that is displayed to the left of the variable name is used to make a variable available in Echoview. If it is not checked, the variable is unavailable. An unavailable variable will not appear on any other menu or in any other context in Echoview with the exceptions of:
