Phylogeny-aware methods

Non-homologous exon alignment by an iterative method (a), and by a phylogeny-aware method (b)

Most multiple sequence alignment methods try to minimize the number of

exons
.

First of such methods started to be developed in 2005 by Löytynoja and Goldman.[1] The same authors released a software called PRANK in 2008.[2] PRANK improves alignments when insertions are present. Nevertheless, it runs slowly compared to progressive and/or iterative methods developed for several years.

In 2012, two new phylogeny-aware tools appeared. One is PAGAN developed by the same team than PRANK.[3] The other is ProGraphMSA developed by Szalkowski.[4] Both were developed independently but share common features, notably the use of graph algorithms to improve the recognition of non-homologous regions, and an improvement in code making these software faster than PRANK.
