Bio::Tools::Blast::Run::LocalBlast.pm - Bioperl module for running Blast analyses locally.
use Bio::Tools::Blast::Run::LocalBlast qw(&blast_local); &blast_local( %named_parameters);
See blast_local() for a description of available parameters.
This module is included with the central Bioperl distribution:
http://bio.perl.org/Core/Latest ftp://bio.perl.org/pub/DIST
Follow the installation instructions included in the README file.
Bio::Tools::Blast::Run::LocalBlast.pm contains methods and data necessary for running Blast sequence analyses on a local machine. This module must be customized for a specific site.
The basic requirements are that it conform to this minimal API:
that accepts a Bio::Tools::Blast.pm object + named parameters as specified by blast_local().
a list of names of files containing the raw Blast reports.
in the arrays @Blast_dbn_local and @Blast_dbp_local.
@Blast_dbn_local
@Blast_dbp_local
The generic version of this module provides some rudimentary logic, but feel free to customize as necessary.
Sometimes it is convenient to write an executable shell script for running a set of Blasts on a local machine. This script can be saved and re-executed as necessary or saved for documentation purposes. This module could provide a convenient way to consolidate the logic necessary for producing such script files or perhaps stubs of script file that could be further modified for Blast-ing specific datasets.
Bio::Tools::Blast::Run::LocalBast.pm is used by Bio::Tools::Blast.pm The development of this is linked with the Blast.pm module and should be updated along with that module.

Usage : @files = blast_local($blast_object, %namedParameters); : This method is exported. Purpose : Run a local Blast analysis on one or more sequences. : This method defines the API for your LocalBlast.pm module. Returns : Array containing a list of filenames of the Blast reports. Argument : $blast_object = object ref for a Bio::Tools::Blast.pm object. : %named parameters: (PARAMETER TAGS CAN BU UPPER OR LOWER CASE) : These are some basic parameters. Supply more as desired. : : -SEQS => ref to an array of Bio::Seq.pm objects. : -SEQ_FILES => ref to an array of strings containing full-path file names. : -PROG => name of blast program (blastp, blastx, etc.) : -DATABASE => name of database (see below.) : -EXPECT => expect value cutoff : -FILTER => sequence complexity filter ('default' or 'none') : -MATRIX => substitution scoring matrix (blast1 only for NCBI server) : -DESCR => integer, number of on-line descriptions (V, 100) : -ALIGN => integer, number of alignments (B, 100) : -GAP => 'on' or 'off' : -OUT_DIR => output directory to store blast result files : Throws : Exception if: : - Cannot obtain parameters by calling _rearrange() on the : first argument, which should be a Bio::Tools::Blast.pm object ref. : - No sequences are provided (objects or files). : - Sequence type is incompatible with Blast program type. : - Database name is not one of the valid names.
