CWP Software Update: CWP/SU Release 38:   23 December 2004  (38th edition)

================================================================
The CWP/SU: Seismic Un*x software package is the free open seismic
software package developed at the Colorado School of Mines.
The package contains many tools for seismic modeling, seismic
processing, and display, as well as research codes in the
diverse fields of seismic imaging, including seismic anisotropy.

Textbook: 
================================================================
 Bleistein, N., J. K. Cohen, and J. W. Stockwell, Jr., [2001],
 Mathematics of Multidimensional Seismic Imaging, Migration,
 and Inversion, (Interdisciplinary Applied Mathematics, V. 13.)
 Springer Verlag, New York.

This textbook presents a comprehensive mathematical treatment
of many types of seismic migration, as well as DMO and other
Fourier-based data mapping processes, written from the vantage point
of inverse scattering theory.  This is a graduate level textbook.
However, parts of the book are appropriate for upper-level 
undergraduates. Several figures in the book were created using 
programs in SU. This book is a must for every geophysicist doing 
seismic or radar imaging.

The book has been out since the end of  Dec 2000. Please see:
http://www.cwp.mines.edu/mmsimi

for further details.

User's Manual Update:
================================================================

Every release brings improvements and extensions to the manual.

There is also a Japanese language version of the New SU Users Manual
avalable at:  http://tansa1.kumst.kyoto-u.ac.jp/suj/
Thanks to Mr. Toshiki Watanabe of the SU Japan User's Group
at the University of Kyoto. The homepage of the SU Japan User's
Group is:   http://tansa1/kumst/kyoto-u.ac.jp/suj/

================================================================
Global change:
================================================================
We have changed all of the fseek and ftell calls to fseeko and
ftello, to permit the implementation of Large Files under both
32 and 64 bit systems.

Additional large file support fixes have been made, thanks to
Reg Beardsley of Unocal.

Demos are currently undergoing an overhaul. The next release
will have real data demos that are suitable for classroom
usage in a seismic data processing class.

================================================================
The Seismic Unix Project depends heavily on contributed code
extensions and bug fixes from the SU users community.
Please note, if you contributed new code, or changes and don't
see it on this list, it will likely be in the next release.

================================================================

================================================================
Resolved issues:
================================================================
Well log support:  A primitive code called suwellrf has been
included. This code may provide a starting point to many variations
on the problem of generating synthetic seismograms from well-logs.

The mglinstall will now work easily on RedHat 7.2 systems.
================================================================
Unresolved Issues:
================================================================
- overhaul of demos, with real data examples-- in progress

- SEG Y REV 1 support-- in progress

- some people have problems with the sfinstall that is necessary
  for installing SEGDREAD

- have trouble with mglinstall on RedHat 9.0 systems. The user may
  need to check to see if he or she is running a card that supports
  opengl, and reinstall (perhaps compile from scratch) the glut 
  libraries from www.opengl.org

-3D anything, modeling, plotting, processing. Contributions of code
 from outside would be of help.

-xmovie: gray only, no colors.

-Well log support:  Reading in well logs for synthetic seismogram
 construction would be helpful. (An individual promised to contribute
 something, but I have not heard back from him.) A primitive
 code "suwellrf" has been included in the current release, but this
 is only the beginning.

-Xtcwp/main/xmovie
 The grid1=, grid2= options cause an abort under linux/XFree86 and
 possibly other platforms.  Message is:
	Error: Cannot perform malloc
 This seems like a compiler error since innocuous changes in the code
 or compiling without optimization makes the problem go away.  We
 distributed the current version with such an innocuous change
 to accomodate this: we changed the dimension of args[] from 100 to 98.

-Refl/main/sureflpsvsh.c - This code works for some input datasets, but
			   still needs bugs fixed.

-no 3D plotting to speak of.
================================================================

Thank you, to all who have helped make CWP/SU Release 38 the best
release so far!
