Iteration of guide tree and HMM can be de-coupled. The accuracy of the program has been considerably improved over earlier Clustal programs, through the use of the HHalign method for aligning profile hidden Markov models. 2010 May 14;5:21. A web interface to ClustalW and other multiple sequence alignment programs is available on In this example HMM guidance PF00042.hmm to the sequences/profiles during the MSA. Clustal Omega is a package for making multiple sequence alignments of amino acid or nucleotide sequences, quickly and accurately. """Command line wrapper for clustal omega.
