NAME

Bio::Network::IO::dip_tab - class for parsing interaction data in DIP tab-delimited format

SYNOPSIS

Do not use this module directly, use Bio::Network::IO. For example:

  my $io = Bio::Network::IO->new(-format => 'dip_tab',
                                 -file   => 'data.dip');

  my $network = $io->next_network;

DESCRIPTION

The Database of Interacting Proteins (DIP) is a protein interaction database (see http://dip.doe-mbi.ucla.edu/dip/Main.cgi). The species-specific subsets of the DIP database are provided in a simple, tab-delimited format. The tab-separated columns are:

   edge     DIP id 
   node A   DIP id 
        node A   optional id
   node A   SwissProt id
   node A   PIR id
   node A   GenBank GI id
   node B   DIP id 
        node B   optional id
   node B   SwissProt id
   node B   PIR id
   node B   GenBank GI id

The source or namespace of the optional id in columns 3 and 8 varies from species to species, and optional ids are frequently absent.

Versions

The first version of this format prepended the identifier with a database name, e.g.:

  DIP:4305E  DIP:3048N     PIR:B64526  SWP:P23487  GI:2313123  ...

The version as of 1/2006 has no database identifiers:

  DIP:4305E  DIP:3048N     B64526  P23487  2313123  ...

This module parses both versions.

METHODS

The naming system is analagous to the SeqIO system, although usually next_network() will be called only once per file.
