Seismic Unix

The CWP/SU Seixmic Un*x (SU) package is a software environment for seismic processing and seismic and wave-propagation related research.

Seismic Unix project is used not only in seismology but in other areas involving time-dependent data, such as Ground Penetrating RADAR.

Installation:

1) read the README's before unbundling cwp.su.all.xx.tar.Z

2) don't install as 'root' (the superuser) (It is possible to damage a system's file structure if the install is not done properly.)

3) begin with the compressed tarfile cwp.su.all.xx.tar.Z in /your/root/path

4) set the CWPROOT environment variable to CWPROOT=/your/root/path

5) put /your/root/path/bin on your working shell path

6) uncompress and untar the compressed tarfile via:

zcat cwp.su.all.xx.tar.Z | tar -xvf -

The code will appear as the single directory /your/root/path/src

7) compile codes via:

cd /your/root/path/src

1) edit the file /your/root/path/src/Makefile.config to agree with the needs of your system.

2) type:

make install (to install the basic set of codes)
make xtinstall (to install the X-toolkit applications)
make finstall (to install the Fortran codes)
make mglinstall (to install the Mesa/ Open GL items) (experimental)
make utils (to install libcwputils) (nonessential)
make xminstall (to install the Motif application)(nonessential)
make sfinstall (to install an improved version of SEGDREAD)

or if remaking:

type: make remake (to remake the basic set of codes)
make xtremake (to remake the X-toolkit applications)
make finstall (to install the Fortran codes)
make mglremake (to install the Mesa/ Open GL items)(experimental)
make uremake (to remake libcwputils.a)(nonessential)(nonessential)
make xmremake (to remake the Motif-based applications)(nonessential)
make sfremake (to remake the improved version of SEGDREAD)

You may have to do some hacking along the way, if the codes fail to compile the first time through. In this event, you may simply type "make" in the directory where you were modifying code. If code appears to have been missed, you may need to
use the "remaking" options.

A screen dump of a successfull install of the current version of the codes on a RedHat Linux based PC is located in the file: "install.successfull"

What is new in this release:

• Numerous bugfixes.

What is new in version 4.3:

• The code is now C99 compliant.
• Phase unwrapping algorithms were added along with assorted bugfixes and code cleanups.
