[Bioperl-l] Bio::Tools::Run::RemoteBlast return codes

[Mark A. Jensen]

True-- blast+ allows remote dbs. I just commited a patch that makes
this easy in StandAloneBlastPlus: specify '-remote => 1' in the
factory, and downstream command calls will take care of it-
MAJ

# ex...
use Bio::Tools::Run::StandAloneBlastPlus;
use Bio::Seq;

$ENV{BLASTPLUSDIR} = $where_it_is;
my $fac = Bio::Tools::Run::StandAloneBlastPlus->new(
    -db_name => 'wgs',
    -remote => 1
    );
my $result = $fac->blastn(
    -query => 
Bio::Seq->new(-seq=>'ggcaacaaacctggtaaagaagacggcaacaagcctggtaaagaagatggcaacaagcct',
       -id=>"proteinA")
    );
