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...
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. BLAST+ can be used with a command line so it can be integrated directly into your workflow.
BLAST stands for Basic Local Alignment Search Tool.The emphasis of this tool is to find regions of sequence similarity, which will yield functional and evolutionary clues about the structure and function of your sequence.
BLAST (ang. Basic Local Alignment Search Tool) – narzędzie bioinformatyczne służące do lokalnego przyrównywania sekwencji aminokwasów białek lub nukleotydów DNA. BLAST umożliwia naukowcom porównywanie żądanej sekwencji z sekwencjami zawartymi w biologicznych bazach danych i ocenę ich podobieństwa.
PSI-BLAST allows users to construct and perform a NCBI BLAST search with a custom, position-specific, scoring matrix which can help find distant evolutionary relationships. Users can specify pattern files to restrict search results using the PHI-BLAST functionality under 'more options'.
