Bio::Network::IO - Class for reading and writing biological network data.
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 => 'psi25' ); my $network = $io->next_network;
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.
The main methods are:
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.
UNIMPLEMENTED.
To read from PSI XML you will need the XML::Twig module, available from CPAN.
User feedback is an integral part of the evolution of this and other Bioperl modules. Send your comments and suggestions preferably to one of the Bioperl mailing lists.
