Dialign-tx is a command line tool to perform multiple alignment of protein or dna sequences. it is a complete reimplementation of the segment-base approach including several new improvements and heuristics that significantly enhance the quality of the output alignments compared to dialign 2.2 and dialign-t. for pairwise alignment, dialign-tx uses a fragment-chaining algorithm that favours chains of low-scoring local alignments over isolated high-scoring fragments. for multiple alignment, dialign-tx uses an improved greedy procedure that is less sensitive to spurious local sequence similarities.

this package contain the score matrices and probability distribution files that dialign-tx needs to align peptidic and nucleic sequences.
