BLAST
BLAST (Basic Local Alignment Search Tool) is an algorithm for comparing biological sequences, such as the amino-acid sequences or the nucleotides of DNA sequences.
BLAST (Basic Local Alignment Search Tool) is a set of similarity search programs. There are aminly two different implementation of BLAST: NCBI BLAST an WU-BLAST, developed at NCBI and Washington University, respectively.
At CEINGE the NCBI BLAST is installed. The NCBI BLAST family of programs includes:
Program | description |
---|---|
blastp | compares an amino acid query sequence against a protein sequence database |
blastn | compares a nucleotide query sequence against a nucleotide sequence database |
blastx | compares a nucleotide query sequence translated in all reading frames against a protein sequence database |
tblastn | compares a protein query sequence against a nucleotide sequence database dynamically translated in all reading frames |
tblastx | compares the six-frame translations of a nucleotide query sequence against the six-frame translations of a nucleotide sequence database. |
