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:

on the View menu, click Filesets.

- OR -

click on the Windows and dialog boxes toolbar.

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 the appropriate tab.

Each fileset is made up of the following sections:

the Data files section
the Calibration section
the Raw variables section

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. During the loading process, the total number of data files and number of data files left to load is shown in the Filesets window title bar.

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.
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.

Click Add to add a new data file. Use the Files format type list to concentrate on specific file types.

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

An icon is displayed next to the data file name.
Note: On subsequent readings using an EVI file, the icon is no longer displayed with the data file name but an entry in the Message dialog box will still be displayed.
A data file specific message is displayed in the Message dialog box.

Click Remove to remove the 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.

Click the Fileset properties icon to open the Fileset Properties dialog box.

Use the mouse and the actions on the Shortcut menu to Copy data file paths to the clipboard to paste into other programs. Select the file(s) to copy and press CTRL+C. See also Fileset window shortcuts.

Calibration section

The Calibration section of the Fielsets 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 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 where available the Historic Calibration 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:

An ECS file that Echoview can't read is flagged a red cross and a message in the Message dialog box, and causes raw variables to become unavailable.
An ECS file may affect multiple EV files or multiple variables. For more information refer to Echoview Calibration Supplement files.

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 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 except via the Show In View dialog box on the Dataflow window.

Click Properties to open the Variable Properties dialog box for the selected variable.

Click Echogram to display an echogram of the selected acoustic variable.

Click Cruise Track to display:

the cruise track for a selected position GPS fixes variable
the along-track display for a selected Sv raw variable.

Click Graph to display a heading graph for a selected heading variable.

Click Table to display a table for a selcted position, attitude or distance variable.

Note: Another way to see and access your raw variables (their properties and echograms) is to use the Variables & Geometry window.
