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 ......阅读全文
