Phylogenetic tree calculations using the Grid with DAG job

The goal of the work is to implement molecular phylogenetic calculations using the Grid paradigm by means of the MrBayes software using Directed Acyclic Graphs (DAG) jobs. In this method, a set of jobs depends on the input or the output of other jobs. Once the runs have been successfully done, all the results can be collected by a specific Perl script inside the defined DAG job. For testing this methodology, we calculate the evolution of papillomavirus with 121 sequences.
