Bio::Matrix::IO - A factory for Matrix parsing

  use Bio::Matrix::IO;
  my $parser = Bio::Matrix::IO->new(-format => 'scoring',
                                    -file   => 'BLOSUMN50');
  my $matrix = $parser->next_matrix;

This is a general factory framework for writing parsers for Matricies. This includes parsing output from distance output like PHYLIP's ProtDist. Additionally it should be possible to fit parsers for PWM and PSSMs once their Matrix objects are written.

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 list. Your participation is much appreciated.

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 of 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   : my $obj = Bio::Matrix::IO->new();
 Function: Builds a new Bio::Matrix::IO object 
 Returns : an instance of Bio::Matrix::IO
 Args    :

 Title   : newFh
 Usage   : $fh = Bio::Matrix::IO->newFh(-file=>$filename,-format=>'Format')
 Function: does a new() followed by an fh()
 Example : $fh = Bio::Matrix::IO->newFh(-file=>$filename,-format=>'Format')
           $matrix = <$fh>;   # read a matrix object
           print $fh $matrix; # write a matrix object
 Returns : filehandle tied to the Bio::SeqIO::Fh class
 Args    :

 Title   : fh
 Usage   : $obj->fh
 Function: Get a filehandle type access to the matrix parser
 Example : $fh = $obj->fh;      # make a tied filehandle
           $matrix = <$fh>;     # read a matrix object
           print $fh $matrix;   # write a matrix object
 Returns : filehandle tied to Bio::Matrix::IO class
 Args    : none

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

 Title   : next_matrix
 Usage   : my $matrix = $matixio->next_matrix;
 Function: Parse the next matrix from the data stream
 Returns : L<Bio::Matrix::MatrixI> type object or undef when finished
 Args    : none

 Title   : write_matrix
 Usage   : $io->write_matrix($matrix)
 Function: Writes a matrix out to the data stream
 Returns : none
 Args    : Array of Bio::Matrix::MatrixI object
          - note that not all matricies can be converted to 
            each format, beware with mixing matrix types and output formats

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

 Title   : _guess_format
 Usage   : $obj->_guess_format($filename)
 Returns : guessed format of filename (lower case)
 Args    : filename
2019-01-01 perl v5.28.1
