[Dart-announce] Ancestral reconstruction with XRate

[Ian H. <ih...@be...>]

A quick software update: xrate now does maximum a-posteriori ancestral 
phylogenetic sequence reconstructions, using the "-ma" option.


Sketchy tests have been done with the following models (the results look 
plausible and it doesn't crash):

-- general reversible point substitution model (DNA)
  -- reconstructed dummy example

-- 3-state Thorne-Goldman-Jones phylo-HMM (protein)
  -- reconstructed Tc1 transposase

-- PFOLD (RNA)
  -- reconstructed hammerhead ribozyme, and a couple others
