 Title   : new
 Usage   : my $obj = Bio::Tools::Run::StandAloneBlast->new();
 Function: Builds a newBio::Tools::Run::StandAloneBlast object
 Returns : Bio::Tools::Run::StandAloneBlast
 Args    : -quiet => boolean # make program execution quiet
           -_READMETHOD => BLAST (default, synonym SearchIO) || blast_pull
                           # the parsing method, case insensitive

Essentially all BLAST parameters can be set via Some of the most commonly used parameters are listed below. All parameters have defaults and are optional except for -p.

  -p Program Name [String]
        Input should be one of "wublastp", "wublastn", "wublastx",
        "wutblastn", or "wutblastx".
  -d  Database [String] default = nr
        The database specified must first be formatted with xdformat.
  -E  Expectation value (E) [Real] default = 10.0
  -o  BLAST report Output File [File Out]  Optional,

 Title   : wublast
 Usage   :  $blast_report = $factory->wublast(t/testquery.fa);
               $input = Bio::Seq->new(-id=>"test query",
               $blast_report = $factory->wublast($input);
              $seq_array_ref = \@seq_array;  # where @seq_array is an array of Bio::Seq objects
              $blast_report = $factory->wublast(\@seq_array);
 Returns :  Reference to a Blast object
 Args    : Name of a file or Bio::Seq object or an array of
           Bio::Seq object containing the query sequence(s).
           Throws an exception if argument is not either a string
           (eg a filename) or a reference to a Bio::Seq object
           (or to an array of Seq objects).  If argument is string,
           throws exception if file corresponding to string name can
           not be found.


 Title   : _generic_local_wublast
 Usage   :  internal function not called directly
