T-Coffee

A Tool For Multiple Sequence Alignments

Notredame, Higgins, Heringa

T-Coffee will combine together several alignments. By default, T-Coffee will generate the 20 best local alignments (lalign) and the best global alignment for each pair of sequences. It will then combine all this information into one multiple sequence alignment. If you request it (Methods), T-Coffee can also generate and combine several multiple alignments using the most common methods (prrp, pima, dialign...), or use your own multiple sequence alignmnents (Data Input).

For a default utilisation, simply paste or upload your sequences in the box 1 on Data Input and press the run button (Limit: 20 sequences 300 residues)
