Build Status

This package contains tools to handle seismic data with the Seis format.

At the moment, it is updated and tested in Julia v1.1.

Installation

To use this package you must first install the Julia programming language. Then, run the Julia application and add the package

julia>using Pkg
julia>Pkg.add("SeisMain")

or

julia>]
pkg> add SeisMain

Finally, in the julia prompt type

julia>using SeisMain

Contents

  1. ReadWrite
  • Exported: SegyToSeis, SeisRead, SeisReadHeaders, SeisWrite, SeisWriteHeaders, SeisCopy, , SeisHeaderInfo, SeisToSegy, SeisRemove
  • Not exported: seis format: InitHeader, GrabHeader, PutHeader, GetNumTraces, ExtractHeader; su format: InitFileHeader, GrabFileHeader, PutFileHeader; segy format: InitSegyHeader, GrabSegyHeader,PutSegyHeader, MapHeaders
  1. Utils
  • SeisBinGeometry, SeisBinHeaders, SeisBinData, SeisPatch, SeisUnPatch, SeisProcess, SeisSort, SeisWindow.

Functions that are not exported can be accessed via SeisMain.ExtractHeader

Use julia help for detail. For example,

julia>?
help?> SegyToSeis

Basic usage

For SeisPlot, please refer here.

The following example produces the figure below.

using SeisMain
using SeisPlot 
run(`mkdir -p data`)
download("http://seismic.physics.ualberta.ca/data/616_79_PR.SGY", "data/616_79_PR.SGY")
SegyToSeis("data/616_79_PR.SGY", "data/616_79_PR.seis")
SeisWindow("data/616_79_PR.seis", "data/616_79_PR_2s.seis", key= ["t"], minval=[0.0], maxval=[2.0])
d, head, extent = SeisRead("data/616_79_PR_2s.seis")
