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 the blast_local manpage() 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 the blast_local manpage(). a list of names of files containing the raw Blast reports. in the arrays "@Blast_dbn_local" and "@Blast_dbp_local". The generic version of this module provides some rudimentary logic, but feel free to customize as necessary.

Script Files
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. Bio::Tools::Blast.pm - Blast object. Bio::Tools::Blast::Run::postclient.pl - Script for accessing remote server. Bio::Tools::Blast::Run::Webblast.pm - Utility module for running Blasts remotely.

blast_local
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.
