T-Coffee is a multiple sequence alignment package. Given a set of
sequences (Proteins or DNA), T-Coffee generates a multiple sequence
alignment. Version 2.00 and higher can mix sequences and structures.
T-Coffee allows the combination of a collection of multiple/pairwise,
global or local alignments into a single model. It also allows to
estimate the level of consistency of each position within the new
alignment with the rest of the alignments.
