Partial Order Alignment for multiple sequence alignment
POA is Partial Order Alignment, a fast program for multiple sequence
alignment (MSA) in bioinformatics. Its advantages are speed,
scalability, sensitivity, and the superior ability to handle branching
/ indels in the alignment. Partial order alignment is an approach to
MSA, which can be combined with existing methods such as progressive
alignment. POA optimally aligns a pair of MSAs and which therefore can
be applied directly to progressive alignment methods such as CLUSTAL.
For large alignments, Progressive POA is 10-30 times faster than
CLUSTALW.
