refinement of multiple sequence alignments. BMC Bioinformatics 2006, 7:499.
Correction
After publication of [1] we have noticed an error in our
manuscript. We have realized that there were some
numbers incorrectly inserted within the Table 1 of the
manuscript [1]. Corrected values are now provided In
Table 1, for six of the numbers that were entered incor-
rectly: the SP scores for References 1, 4 and 5 under
Muscle reference alignment (REFINER refinement align-
ment) and, SP scores for References 2, 3 and 5 under
T-Coffee reference alignment (Default refinement
