lagan - 2.0-9 main

Lagan takes local alignments generated by CHAOS as anchors, and limits
the search area of the Needleman-Wunsch algorithm around these anchors.
.
Multi-LAGAN is a generalization of the pairwise algorithm to multiple
sequence alignment. M-LAGAN performs progressive pairwise alignments,
guided by a user-specified phylogenetic tree. Alignments are aligned to
other alignments using the sum-of-pairs metric.
