WebOn each board a pair scores two match-points for each other pair with a lower score, and one match-point for each other pair with the same score. The opponents receive the complement score. For example if a board is played a total of 11 times then a ‘top’ on the board would be 20 match-points (the ‘top’ pair beating 10 other pairs x 2). WebSP: sum-of-pairs score Score each MSA site and then add up the scores over all sites Penalize mismatches and gaps Favor matches The per-site score is defined as the sum of all pairwise scores between characters of a site WebIn order to create multiple sequence alignment, we need a scoring system.
