- Basic Local Alignment Search Tool - BLAST
The Basic Local Alignment Search Tool (BLAST) finds regions of local similarity between sequences The program compares nucleotide or protein sequences to sequence databases and calculates the statistical significance of matches
- BLAST+ executables — BLASTHelp documentation
The NCBI provides a suite of command-line tools to run BLAST called BLAST+ This allows users to perform BLAST searches on their own server without size, volume and database restrictions
- Nucleotide BLAST: Search nucleotide databases using a nucleotide query
This title appears on all BLAST results and saved searches Enter one or more queries in the top text box and one or more subject sequences in the lower text box Then use the BLAST button at the bottom of the page to align your sequences

- Frequently Asked Questions — BLASTHelp documentation
The BLAST programs are command line programs that run BLAST searches against local, downloaded copies of the NCBI BLAST databases, or against custom databases formatted for BLAST The programs can handle either a single large file with multiple FASTA query sequences, or you can create a script to send multiple files one at a time

Overview ¶ What is BLAST? The Basic Local Alignment Search Tool (BLAST) finds regions of local similarity between sequences The program compares nucleotide or protein sequences to sequence databases and calculates the statistical significance of matches
- BLAST Program Selection Guide
This blast page allows you to blast a given set of sequences to find matches to those sequences genes represented by entries in the GEO database Matching hits will have "E" gif icons links to corresponding entries in GEO
- Needleman-Wunsch alignment of two nucleotide sequences - BLAST
Local alignments algorithms (such as BLAST) are most often used A global alignment should only be used on sequences that share significant similarity over most of their extents, and then it will sometimes return a better presentation
