Parallelised refinement using Frealix

Refinements can easily be parallelised by distributing filaments across processing nodes, and then compiling the results.

A Ruby script, flx_wrap.rb is distributed with Frealix to facilitate this. It can use the Sun Grid Engine (SGE) or a user-supplied list of nodes which it will access over ssh, or both. Many rounds of refinement can be run, with the option to vary the target resolution of the refinement, as well as the maximum spatial frequency used by the scoring function.

To get help on using this script, use the --help command line option:
