Opal is software for aligning multiple biological sequences.

In benchmark tests, Opal aligns sequences with good accuracy. On DNA, accuracy is similar to that of MAFTT and Muscle; on protein, accuracy is similar to MAFFT, and better than Muscle. Details of the software are available in this paper (from the Proceedings of ISMB 2007).
