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
