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.
