AYB README File
===============

Prerequisites
-------------
The following utilities and libraries must be installed to make/run the program:

Utilities::
- gcc (GNU C compiler; part of GNU Compiler Collection)
- gfortran (GNU Fortran compiler; part of GNU Compiler Collection)
  (not required from v2.05)
- make (GNU make utility)

Libraries::
- BLAS (Basic Linear Algebra Subprograms)
- LAPACK (Linear Algebra PACKage)
- zlib (general purpose compression library)
- bzip2 (alternative compression library)

To make the program, the relevant header files for each of these libraries
must also be present. The header files are usual contained in the
-devel package corresponding to each library, for example: blas-devel

Obtaining AYB
-------------
Source code is freely available to download from <http://www.ebi.ac.uk/goldman-srv/AYB/>


Build AYB
---------
unzip the archive:

---------------------------------------------
$ tar -xzf AYB_current.tgz
---------------------------------------------

Go to the src directory. The makefile is suitable for both generic Linux and Mac Os-X.

---------------------------------------------
$ make
---------------------------------------------

The AYB executable will be in the bin directory.

{nbsp}

Notes::
If OpenMP libraries are not available then the dependency can be removed by 
deleting the -fopenmp option from the makefile.


Developing
----------

AYB Developer documentation is generated by running doxygen from the src directory. 
The index file is created in ../../doc from the src directory.

The AYB_test download contains the module test inputs.
