What is T-Coffee?

T-Coffee is a multiple sequence alignment package. You can use T-Coffee to align sequences or to combine the output of your favorite alignment methods (Clustal, Mafft, Probcons, Muscle, etc.) into one unique alignment (M-coffee).

T-Coffee can align Protein, DNA and RNA sequences. It is also able to combine sequence information with protein structural information (Expresso), profile information (PSI-Coffee) or RNA secondary structures (R-Coffee).
