OCTAVE TRAPLT

This is the octave version of TRAPLT. The following files are required to be in the directory where octave is started.

• bsegin.m Reads traces from BSEGY files
• segyinfo.m Reads header information from BSEGY files
• traplt.m Actually does the plotting

 Start an octave session and then type 
	traplt

You will be prompted for a file name, channel
phase reference, and maximum frequency to
display.

First shows a plot of the selected trace, mouse
used to pick time zero for phase. Click OK then use mouse.

Uses FFT for amplitude spectrum
