D、E值:代表被比对的两个序列不相关的可能性。【The E value decreases exponentially as the Score (S) that is assigned to a match between two sequences increases】。E值最低的最有意义,也就是说序列的相似性最大。设定的E值是我们限定的上限,E值太高的就不显示了

An exact solution to the global alignment problem was developed by Saul Needleman and Christian Wunsch in 1970, by applying dynamic programming to find the optimal alignment between two sequences. In 1981, Temple Smith and Michael Waterman extended this dynamic programming approach to solve the...
BLASTN, TBLASTX, or combinations of both are used to locate high-scoring segment pairs (HSPs) between two sequences from which pairwise similarities and distances are computed in different ways resulting in a total of 96 GBDP variants. The suitability of these distance formulae for phylogeny ...
BLAST use a partial algorithm to find the similar sequences between two sequences. There are some common used program in the BLAST : BLASTP, BLASTX, BLASTN, TBASTN, TBLASTX. Today, BLAST and FASTA is two of the most popular comparing program, which is widely used in the biology field....

can also be used to specify, instead, a "score density." The latter is equivalent to the BLAST score divided by the alignment length. If "S" is given as a number between 0 and 3, it is interpreted as a score density threshold; otherwise it is interpreted as a percent identity threshol...

Blat is an alignment tool like BLAST, but it is structured differently. Blat produces two major classes of alignments: at the DNA level between two sequences that are of 95% or greater identity, but which may include large inserts.
