IPAS is a new and practial protein multiple sequence alignment
algorithm based on iterative progresive alignment algorithm Assessed on BAliBASE 3.0, PREFAB 4.0,
SABMARK 1.65, and OXBENCH, MSAProbs achieves the statistically
highest alignment accuracy, compared to ClustalW 2.0.10, MAFFT 6.717(
using L-INS-i with --maxiterate = 1000), MUSCLE 3.8.31, ProbCons 1.12,
and Probalign 1.3.
