Geopsy: Waveform Scripting Language

The scripting language is based on the ECMAScript scripting language, as defined in standard ECMA-262. Basic structures, variables,... are described in this document. Other references:

• A quick reference guide
• A more comprehensive tutorial (JavaScript which is also an ECMAScript)

Geopsy provides several additional functions for processing signals details here below

save

Syntax

 save(string tag);

Description

Saves the current signals onto the stack under tag. tag is an arbitrary string used to restore() previously saved signals. This function is systematically produced when using the waveform menu items.

Examples

 filter();
 save("Low pass 10 Hz");
 whiten();
 save("Whiten");
 restore("Low pass 10 Hz");
 clipStddev();

signalCount

Syntax

 integer signalCount();

Description

Returns the number of signals to process.

Examples

Sets the sampling frequency to 100 Hz for all signals

 n=signalCount();
 for(i=0;i<n;i++) {
   setHeader(i, "DeltaT", 0, 0.01);
 }
