Correction to Chakrabarti S, Lanczycki CJ, Panchenko AR, Przytycka TM, Thiessen PA and Bryant SH: State of the art: refinement of multiple sequence alignments. BMC Bioinformatics 2006, 7:499.
After publication of  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 . Corrected values are now provided In Table 1, for six of the numbers that were entered incorrectly: the SP scores for References 1, 4 and 5 under Muscle reference alignment (REFINER refinement alignment) and, SP scores for References 2, 3 and 5 under T-Coffee reference alignment (Default refinement alignment). However, this does not affect our original interpretation of the data presented in our original publication in any way. We regret any inconvenience that this inaccuracy might have caused.
