1. Requirements 
=======================================================================================

MO-Phylogenetics has been developed in Unix machines (Ubuntu and MacOS X) as well as in
Windows (MinGW) using the G++ (4.4.7) compiler. The make utility has been used to compile the
software package.

MO-Phylogenetics is based on jMetalCpp and requires install two frameworks:

1) Bio++: a set of C++ libraries for Bioinformatics, including sequence analysis, phylogenetics, molecular evolution and population genetics. Home Page:  http://biopp.univ-montp2.fr/

2) PLL - Phylogenetic Likelihood Library: a highly optimized, parallized software library to ease the development of new software tools dealing with phylogenetic inference. 
Home Page: Phylogenetic Likelihood Library http://www.libpll.org/

Bio++ also requeries the CMake utility and Pll requeries Autoreconf utility.

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

=======================================================================================
2. Installing MO-Phylogenetics
=======================================================================================

Copy the compressed file to the location where you want to install MO-Phylogenetics and
unzip it.

Then, run the install.sh with the following command:
  %sh install.sh

This install all the libraries needed: Bio++ (Bpp-Core, Bpp-Seq and Bpp-Phyl) and Pll.
Add the path of the new libraries installed in your .bashrc file

For Bio++:

   export CPATH=$CPATH:MOPhylogenetics_path/lib/Bpp/include    
   export LIBRARY_PATH=$LIBRARY_PATH:MOPhylogenetics_path/lib/Bpp/lib   
   export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:MOPhylogenetics_path/lib/Bpp/lib  

For Pll:

   export CPATH=$CPATH:MOPhylogenetics_path/lib/Pll/src/include    
   export LIBRARY_PATH=$LIBRARY_PATH:MOPhylogenetics_path/lib/Pll/src/lib   
   export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:MOPhylogenetics_path/lib/Pll/src/lib  

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


=======================================================================================	
3. Executing MO-Phylogenetics
=======================================================================================

The main binary is in the subfolder 'bin'. Enter this folder to execute MO-Phylogenetics.
	
  % cd bin
  % ./MOPhylogenetics param= parametersfile

The parameterfile is the filename wich has all the parameters requeried to execute the program. For example, to execute the program using one of our test problem 500 sequences dataset, type the following command:
	
  %./MOPhylogenetics param=parameters/params500.txt

The parameters to solve the state-of-the-art problems are defined in some files saved into the paramaters folder, and also are included the datasets (nucleotide sequences), partition model file and the initial user trees perfomanced by a bootstrap techniques using PhyML and DNAPars software.

# ********** Phylogenetic Optimization  ***********

High-level Strategies for searching the tree space: h2 y h1

H1: This strategy is based on the theoretical perspective of the strong relation between
parsimony and likelihood (minimizing the parsimony score is equivalent to
maximizing the likelihood under some assumptions), and searchs bi-objective phylogenetic trees applying topological moves using the Parametric Progressive Neighbourhood (PPN) technique (Go¨effon et al.,2008) to minimizing the parsimony and with this maximizing the likelihood
simultaneously; furthermore, with the aim of improve the likelihood, optimize all branch lengths affected for the topological moves. 

H2: This strategy is a parametric combination of two techniques that optimize both
criteria separately, for parsimony uses PPN technique applying topological
moves and adjusting the branch lengths affected, and for the likelihood uses a topological rearrange method provided by the Phylogenetic Likelihood Library (PLL).

Parameters:

optimization.method 			= h2 or h2
