INSTALLATION
-------------

1) To compile and link the code you first have to set the ROOT variable in the Make_include file which can be found in the directory where you have found this README.
You can use Make_include_template as a first start: cp Make_include_template Make_include

2) Check the compiler and CFLAGS options in the file Make_include and adapt to the system you are using. The default options are set for a the GNU C-compiler on a Linux system. A Fortran or C++ compiler are not needed to compile the code. The Makefile has been tested with GNU make.

3) If the compiler options are set in the Make_include file you can type

> make

and the Makefile will make:

- FFT library
- fdelmodc
- marchenko
- utils

The libraries will be placed in the lib/ directory and the executables in the bin/ directory.

To use the executables don't forget to include the pathname in your PATH:

bash/sh:
export PATH='path_to_this_directory'/bin:$PATH:
csh:
setenv PATH 'path_to_this_directory'/bin:$PATH:

*** FOR SU USERS:
If you want to use the .su files with SU from CWP:
==> Please make sure that SU is compiled without XDR (in $CWPROOT/Makefile.config make sure that XDRFLAG is NOT set). The SU output files of fdelmodc are all based on local IEEE data.
***

> make clean

Finite Difference Modeling: FDELMODC
------------------------------------
If the compilation has finished without errors and produced an executable called bin/fdelmodc you can run one of the demo programs by running

> ./fdelmodc_plane.scr

in the directory fdelmodc/demo/

The demo directory contains scripts which demonstrate the different possibilities of the modeling program.

To reproduce the Figures shown in the GEOPHYICS manuscript "Finite-difference modeling experiments for seismic interferometry" the scripts in FiguresPaper directory can be used. Please read the README in the FiguresPaper directory for more instructions and guidelines.

Marchenko method : MARCHENKO
----------------------------
If the compilation has finished without errors and produced an executable called bin/marchenko you can run one of the demo programs by running a set of scripts that are explained in a README in one of the directories marchenko/demo/*

To reproduce the Figures shown in the GEOPHYICS paper "Implementation of the Marchenko method" the scripts in marchenko/demo/oneD directory can be used. The README in this directory gives more instructions and guidelines.

To reproduce the Figures shown in the Scientific Reports paper "Virtual acoustics in inhomogeneous media with single-sided access" the scripts in marchenko/demo/ScientificReports directory can be used. The README in this directory gives more instructions and guidelines.

MDD
---
The MDD kernels depend on BLAS and LAPACK calls. Free downloads of these libraries can be found on

https://www.netlib.org/blas/index.html
https://www.netlib.org/lapack/index.html

If you are running on Intel processors you can download (for free) Intel's highly optimised MKL package:

https://software.intel.com/en-us/mkl/choose-download

MISC
----
Other make commands which can be useful:

make clean : removes all object files, but leaves libraries and executables
make realclean: removes also object files, libraries and executables.

UPDATES AND LATEST VERSION
--------------------------
The latest version of the source code and manual can be found at:

http://www.xs4all.nl/~janth/Software/Software.html

or at github:

git clone https://github.com/JanThorbecke/OpenSource.git
git clone git://github.com/JanThorbecke/OpenSource.git

The code is used by many different people and if there is a request for a new option in the code, then I will try to implement, test and make it available.
