HowtouseBasicLocalAlignmentSearchTool(BLAST)
DescriptionThe BLAST algorithm was developed as a way to perform DNA and protein sequence similarity searches by an algorithm that is faster than FASTA but considered to be equally as sensitive. Both of these methods follow a heuristic (tried-and-true) method that almost always works to find related sequences in a database search, but does not have the underlying guarantee of an optimal ......閱讀全文

Blast基本介紹
什么是BLAST?BLAST (Basic Local Alignment Search Tool)是一套在蛋白質數據庫或DNA數據庫中進行相似性比較的分析工具。BLAST程序能迅速與公開數據庫進行相似性序列比較。BLAST結果中的得分是對一種對相似性的統計說明。BLAST 采用一種局部的算法獲得兩
