NAME

Bio::Network::IO - Class for reading and writing biological network data.

SYNOPSIS

This is a modules for reading and writing protein-protein interaction and creating networks from this data.

  # Read protein interaction data in some format
  my $io = Bio::Network::IO->new(-file => 'bovine.xml',
                                 -format => 'psi' );
  my $network = $io->next_network;

DESCRIPTION

This class is analagous to the SeqIO and AlignIO classes. To read in a file of a particular format, file and format are given as key/value pairs as arguments. The Bio::Network::IO checks that the appropriate module is available and loads it.

At present only the DIP tab-delimited format and PSI XML format are supported.

METHODS

The main methods are:

$net = $io->next_network

The next_network method does not imply that multiple networks are contained in a file, this is to maintain a consistent nomenclature with Bioperl methods like $seqio->next_seq and $alnio->next_aln.

$io->write_network($network)

UNIMPLEMENTED.

REQUIREMENTS

To read or write from PSI XML you will need the XML::Twig module, available from CPAN.
