HPC-BLAST: NCBI compliant multinode and multicore BLAST wrapper. Distributed with the latest version of BLAST, this wrapper facilitates parallelization of the algorithm on modern hybrid architectures with many nodes and many cores within each node.

formatdb must be used in order to format protein or nucleotide source databases before these databases can be searched by BLAST. [2] The source database may be in either FASTA or ASN.1 format. Although the FASTA format is most often used as input to formatdb, the use of ASN.1 is advantageous for those who are using ASN.1 as the common source ...
NCBI has a "Magic-BLAST" tool built around BLAST for this purpose. [31] Comparison When working with genes, BLAST can locate common genes in two related species, and can be used to map annotations from one organism to another. Classifying taxonomy BLAST can use genetic sequences to compare multiple taxa against known taxonomical data.
The NCBI assigns a unique identifier (taxonomy ID number) to each species of organism. [5] The NCBI has software tools that are available through web browsers or by FTP. For example, BLAST is a sequence similarity searching program. BLAST can do sequence comparisons against the GenBank DNA database in less than 15 seconds.
A workflow can be run using the graphical interface or launched from the command line. The graphical interface also allows controlling the workflow execution, storing the parameters, and so on. There is an embedded library of workflow samples to convert, filter, and annotate data, with several pipelines to analyze NGS data developed in ...
Many of Biopython's modules contain command line wrappers for commonly used tools, allowing these tools to be used from within Biopython. These wrappers include BLAST, Clustal, PhyML, EMBOSS and SAMtools. Users can subclass a generic wrapper class to add support for any other command line tool.
The NCBI defined a standard for the unique identifier used for the sequence (SeqID) in the header line. This allows a sequence that was obtained from a database to be labelled with a reference to its database record. The database identifier format is understood by the NCBI tools like makeblastdb and table2asn. The following list describes the ...
The guide tree in the initial versions of Clustal was constructed via a UPGMA cluster analysis of the pairwise alignments, hence the name CLUSTAL. [11] cf. [12] The first four versions of Clustal were numbered using Arabic numerals (1 to 4), whereas the fifth version uses the Roman numeral V. [11] cf. [13] [5] The next two versions proceed alphabetically using the Latin alphabet, with W ...
