Description

Name

Enter a name or accept the default.

See also: Supported characters for names.

Derive raw variables

The setting is available when there are no data files in the fileset.

Derive raw variable methods include:

• Using transducer frequency
• This method considers transducer number, channel number and transducer frequency when deriving raw variables.
• Using transducer/channel number
• This method considers transducer number and channel number when deriving raw variables.
• Pre-Echoview 9 EV files are assigned this method.

For examples of how these methods assign ping data refer to About filesets: Deriving raw variables.

Create and/or associate transducers based on frequency when new raw variables are derived

This setting is available to existing or new EV files. Select this setting to create transducers based on transducer frequency when new raw variables are derived. The transducers are displayed, with fileset and transducer frequency information, on the Dataflow window.

Time Offset

The time offset may be used if two sets of data have been recorded from devices whose time base differs.

Add offsets forward in time.

Subtract offsets back in time.

The time shift is specified by values for:

• Days
• Hours
• Minutes
• Seconds
• Milliseconds

Note: The Time offset is similar to the Ping time shift operator's Shift pings by time setting.

Notes

Annotations can be entered.
