5. Viewers

Any subset of the total ensemble of opened signals can be created with the "drag and drop" mechanism explained in section Selecting signals. The subsets are visualised through tables, graphics and maps detailed in this chapter:

• 5.1. Table
• 5.2. Graphic
• 5.3. Map

The various actions that can be performed with a subset of signals (either a table, a graphic or a map) are described here after.

File export

Select item "Export" from menu "File". You will be prompted to select the file format. Various formats are currently proposed:

• SEG2
• SAC: little or big endian
• SU: little or big endian
• ASCII: one or multi columns
• Surf: surface-wave inversion from R. Herrmann
• SAF: Sesame ASCII file format
• WAV: PCM sound file, to create sound from seismic signals (generally requires a strong modification of the sampling frequency: 44 kHz for usual music records).

Not all these formats support multiple signals in a single file. If those case you will be prompted to select an export directory or to enter the names manually.

Waveform

Basic signal processing can be performed on all the signals of the active viewer. These processing are gathered in menu "Waveform". For details, refers to chapter Basic signal processing.

Tools

Tools are developed as plug-ins and provide specific signal processing (menu "Tools"). As for basic signal processing, the selected tool is applied to the signals of the active viewer. For details, refers to chapter Specific processing tools.

"Edit" menu

All menu items in "Edit" menu apply to all signals contained in the active viewer.

Sorting signals

This feature is explained in section Sorting signals.

Editing headers

This feature helps you modify the header information by the means of generic formulas.

Editing receivers

This feature helps you modify the coordinates of receivers. The signal names are considered as names of stations to which corresponds only one unique set of coordinates.

Creating new groups

This feature is explained in section Creating a new group.
