Gibbs motif/site sampler  

A program for identifying conserved segments in protein sequences. It is particularly useful for identifying internal repeats.  Gibbs sampling is named after the physicist Josiah Willard Gibbs, in reference to an analogy between the sampling algorithm and statistical physics.

Auxiliary programs: CDD2MGS, AddPhylum, PurgeMSA and ConvertMSA
