Blast max score 意味

Web国立研究開発法人 科学技術振興機構 WebThe bit-score is the required size of a sequence database in which the current match could be found by chance. It is derived from the raw alignment score; the higher the score, the better the alignment. Total score: the sum of the alignment scores of all of the segments from the sequence. The higher the score, the better the alignment.
