man Bio::Tools::Run::EMBOSSacd (3): class for EMBOSS Application qualifiers

SYNOPSIS

use Bio::Factory::EMBOSS;
# get an EMBOSS application object from the EMBOSS factory
$factory = Bio::Factory::EMBOSS->new();
$application = $factory->program('embossversion');
# run the application with an optional hash containing parameters
$result = $application->run(); # returns a string or creates a file
print $result . "\n";
$water = $factory->program('water');
# here is an example of running the application
# water can compare 1 seq against 1->many sequences
# in a database using Smith-Waterman
my $seq_to_test; # this would have a seq here
my @seqs_to_check; # this would be a list of seqs to compare
# (could be just 1)
my $wateroutfile = 'out.water';
$water->run({ -sequencea => $seq_to_test,
-seqall => \@seqs_to_check,
-gapopen => '10.0',
-gapextend => '0.5',
-outfile => $wateroutfile});
# now you might want to get the alignment
use Bio::AlignIO;
my $alnin = Bio::AlignIO->new(-format => 'emboss',
-file => $wateroutfile);
while( my $aln = $alnin->next_aln ) {
# process the alignment -- these will be Bio::SimpleAlign objects
}

DESCRIPTION

The EMBOSSacd represents all the possible command line arguments that can be given to an EMBOSS application.

Do not create this object directly. It will be created and attached to its corresponding Bio::Tools::Run::EMBOSSApplication if you set

  $application->verbose > 0

Call

  $application->acd

to retrive the Bio::Tools::Run::EMBOSSApplication::EMBOSSacd object.

See also Bio::Tools::Run::EMBOSSApplication and Bio::Factory::EMBOSS.
