WebThe BLAST score is scoring local ungapped alignments. The theory of scoring here is well understood. The database sequences are assumed to be evolutionary unrelated, i.e. independent of one another. The alignment starts at specific positions along query and database record. The score matrix must give, on the average, a negative (a,b) score. http://thegrantlab.org/bio3d/reference/blast.pdb.html
