PSI-BLAST allows the user to build a PSSM (position-specific scoring matrix) using the results of the first BlastP run. PHI-BLAST performs the search but limits alignments to those that match a pattern in the query.
Learn the meaning of blast as a verb, noun and exclamation in English, with synonyms, antonyms and idioms. Find out how to use blast in different contexts, such as explosions, noises, criticism, sports and parties.
ElasticBLAST is a suite of command line applications that distributes your BLAST searches across multiple instances in the cloud. It can run large numbers of queries faster than BLAST+ on a single machine and manage cloud resources for you.
BLAST is one of the most widely used bioinformatics programs for sequence searching. [4] It addresses a fundamental problem in bioinformatics research. The heuristic algorithm it uses is much faster than other approaches, such as calculating an optimal alignment.
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).
Awash in a sea of data, how do scientists identify the function of a newly cloned gene? Online resources like the Basic Local Alignment Search Tool (BLAST) provide a helping hand.
