Bio::Assembly::IO - Handler for Assembly::IO Formats

    use Bio::Assembly::IO;
    $in  = Bio::Assembly::IO->new(-file=>"<inputfilename",
                                  -format=>'phrap');
    $out = Bio::Assembly::IO->new(-file=>">outputfilename",
                                  -format=>'phrap');
    while ( my $scaffold = $in->next_assembly() ) {
       # do something with Bio::Assembly::Scaffold instance
       # ...
       $out->write_assembly(-scaffold => $scaffold);
    }
    $in->close;
    $out->close;

Bio::Assembly::IO is a handler module for formats in the Assembly::IO set (e.g. Bio::Assembly::IO::phrap).

User feedback is an integral part of the evolution of this and other Bioperl modules. Send your comments and suggestions preferably to the Bioperl mailing lists Your participation is much appreciated.
  bioperl-l@bioperl.org                  - General discussion
  http://bioperl.org/wiki/Mailing_lists  - About the mailing lists

Please direct usage questions or support issues to the mailing list:
bioperl-l@bioperl.org
rather than to the module maintainer directly. Many experienced and reponsive experts will be able look at the problem and quickly address it. Please include a thorough description of the problem with code and data examples if at all possible.

Report bugs to the Bioperl bug tracking system to help us keep track the bugs and their resolution. Bug reports can be submitted via the web:

The rest of the documentation details each of the object methods. Internal methods are usually preceded with a _

 Title   : new
 Usage   : $stream = Bio::Assembly::IO->new( -file   => $filename,
                                             -format =>'format'    )
 Function: Returns a new assembly stream
 Returns : A Bio::Assembly::IO::Handler initialised
           with the appropriate format
 Args    : -file   => $filename
           -format => format

 Title   : format
 Usage   : $format = $stream->format()
 Function: Get the assembly format
 Returns : assembly format
 Args    : none

 Title   : next_assembly
 Usage   : $scaffold = $stream->next_assembly()
 Function: Reads the next assembly object from the stream and returns it.
 Returns : a Bio::Assembly::ScaffoldI compliant object
 Args    : none

 Title   : next_contig
 Usage   : $contig = $stream->next_contig()
 Function: Reads the next contig or singlet from the stream and returns it.
 Returns : a Bio::Assembly::Contig or Bio::Contig::Assembly::Singlet
 Args    : none

  Title   : write_assembly
  Usage   : $stream->write_assembly($assembly)
  Function: Write the assembly object in desired format. This method calls
            write_header(), write_contigs() and write_footer() internally.
  Returns : 1 on success, 0 for error
  Args    : A Bio::Assembly::Scaffold object

  Title   : write_header
  Usage   : $stream->write_header($assembly)
  Function: Write the start of the assembly file. It can be called at any time,
            not when starting to write the assembly file. 
  Returns : 1 on success, 0 for error
  Args    : A Bio::Assembly::Scaffold object or ... (check the specific format
            driver for more details)

  Title   : write_contig
  Usage   : $stream->write_contig($contig)
  Function: Write a contig object in the desired format.
  Returns : 1 on success, 0 for error
  Args    : A Bio::Assembly::Contig object
  Title   : write_footer
  Usage   : $stream->write_footer($assembly)
  Function: Write the start of the assembly file.
  Returns : 1 on success, 0 for error
  Args    : A Bio::Assembly::Scaffold object or ... (check the specific format
            driver for more details)

 Title   : _load_format_module
 Usage   : *INTERNAL Assembly::IO stuff*
 Function: Loads up (like use) a module at run time on demand
 Example :
 Returns :
 Args    :

 Title   : _guess_format
 Usage   : $obj->_guess_format($filename)
 Function: guess format based on file suffix
 Example :
 Returns : guessed format of filename (lower case)
 Args    :
 Notes   : formats that _filehandle() will guess includes
           ace, phrap and tigr at the moment

    Title   : _sort
    Usage   : @sorted_values = $ass_io->_sort(@values)
    Function: Sort a list of values naturally if Sort::Naturally is installed
              (nicer), lexically otherwise (not as nice, but safe)
