Pairwise string alignment in Python My contribution will be: * Code cleanup * Support of arbitrary alphabets of input strings (no similarity matrix) * Support of both variants: 1. Smith-Waterman = local alignment 2. Needleman-Wunsch = global alignment Original Smith-Waterman implementation in Python was forked from http://narnia.cs.ttu.edu/drupal/node/104 by Forrest Sheng Bao http://fsbao.net a free software licensed under GNU General Public License (GPL) A copy of GPL version 3 has been placed into the file LICENSE.
