Hello,
I've re-written the entire thing from scratch in Ruby, making it much faster, and able to handle extremely large datasets. This also means it's probably best-used once you're more familiar with phylogenetics. I'd advise new users to start with pG1, and then, once they're comfortable, move up from there.
The zooplankton example shows how to build a 5-gene phylogeny of ~200 species; hopefully that gives an indication of the increased speed of the program. It now supports multiple processors, and the new programs ExaML and ExaBayes.
Let me know if you have any feature requests or bug reports.
Cheers,
Will
