Bio::Factory::EMBOSS - EMBOSS application factory class
# Get an EMBOSS factory
use Bio::Factory::EMBOSS;
$f = Bio::Factory::EMBOSS -> new();
# Get an EMBOSS application object from the factory
$water = $f->program('water') || die "Program not found!\n";
# Here is an example of running the application - water can
# compare 1 sequence against 1 or more sequences using Smith-Waterman.
# Pass a Sequence object and a reference to an array of objects.
my $wateroutfile = 'out.water';
$water->run({-asequence => $seq_object,
-bsequence => \@seq_objects,
-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
}
The EMBOSS factory class encapsulates access to EMBOSS programs. A factory
object allows creation of only known applications.
If you want to check command line options before sending them to the program set
$prog->verbose to positive integer. The value is passed on to programs
objects and the ADC description of the available command line options is
parsed and compared to input.

The rest of the documentation details each of the object methods. Internal
methods are usually preceded with a _
Title : location
Usage : $embossfactory->location
Function: get/set the location of EMBOSS programs.
Valid values are 'local' and 'novella'.
Returns : string, defaults to 'local'
Args : string
Title : program
Usage : $embossfactory->program('program_name')
Function: Creates a representation of a single EMBOSS program and issues a
warning if the program was not found.
Returns : Bio::Tools::Run::EMBOSSApplication object or undef
Args : string, program name
Title : $self->version
Usage : $embossfactory->version()
Function: gets the version of EMBOSS programs
Throws : if EMBOSS suite is not accessible
Returns : version value
Args : None
These methods allow the programmer to query the EMBOSS suite and find out which
program names can be used and what arguments can be used.
Title : program_info
Usage : $embossfactory->program_info('emma')
Function: Finds out if the program is available.
Returns : definition string of the program, undef if program name not known
Args : string, prgramname
Do not call these methods directly
Title : _program_list
Usage : $embossfactory->_program_list()
Function: Finds out what programs are available.
Writes the names into an internal hash.
Returns : true if successful
Args : None
