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.
Select the sequence database to run searches against. No BLAST database contains all the sequences at NCBI. BLAST databases are organized by informational content (nr, RefSeq, etc.) or by sequencing technique (WGS, EST, etc.). more...
Magic-BLAST ¶. Magic-BLAST is a tool for mapping large next-generation RNA or DNA sequencing runs against a whole genome or transcriptome. Read more about Magic-BLAST at NCBI Magic-BLAST Documentation. Installers and source code are available from https://ftp.ncbi.nlm.nih.gov/blast/executables/magicblast/LATEST.
ElasticBLAST starts instances for you, provisions them with BLAST software and loads the BLAST database you requested. ElasticBLAST runs your batches on the instances, queuing up the work with cloud native scheduling software (Kubernetes on GCP and AWS Batch on AWS).

BLAST is available on the web on the NCBI website. Different types of BLASTs are available according to the query sequences and the target databases. Alternative implementations include AB-BLAST (formerly known as WU-BLAST), FSA-BLAST (last updated in 2006), and ScalaBLAST.
The program compares nucleotide or protein sequences to sequence in a database and calculates the statistical significance of the matches. This chapter first provides an introduction to BLAST and then describes the practical application of different BLAST programs based on the BLAST Quick Start mini-course (www.ncbi.nlm.nih.gov/Class/minicourses).
Jul 1, 2004 · Basic Local Alignment Search Tool (BLAST) is a sequence similarity search program that can be used via a web interface or as a stand-alone tool ( 1, 2 ). There are several types of BLAST to compare all combinations of nucleotide or protein queries with nucleotide or protein databases.
