Detailed Description

Seismic traces.

A seismic trace is composed of trace info and trace data. The trace data consists of one or more components. These are represented by a set of buffers, interpreted by DataInterpreters.

SeisTrc* SeisTrc::getExtendedTo	(	const ZGate &	,
		bool	usetrcvals = true
	)			const

Extends (or shrinks) trace to ZGate Added values can be first/last value of input, or zeros

bool SeisTrc::getFrom	(	Socket &	,
		BufferString *	err = 0
	)

If !err, errors are handled trough the socket.

SeisTrc* SeisTrc::getRelTrc	(	const ZGate &	,
		float	sr = mUdf(float)
	)			const

Resample around pick. No pick: returns null. ZGate is relative to pick
