my $hInteractions = $oTransport->query('interactorA'); my $hInteractions = $oTransport->query('interactorA', 'interactorB');

A data transport exposing interactions stored in a SIF file, along with attributes stored in Cytoscape attribute files. Access is via the 'query' method.

Each line of a Simple Interaction Format (SIF) file describes one or more binary interactions, and takes the form: nodeA lineType nodeB [nodeC ...]

This example describes a protein-protein interaction between interactorA and interactorB: interactorA pp interactorB

This example describes three separate interactions, each involving interactorA: interactorA pp interactorB interactorC interactor D

Node attribute files may be used to add DAS 'detail' elements to interactors: description interactorA = An example interactor interactorB = Another example of an interactor ...

Edge attribute files may be used to add DAS 'detail' elements to interactions: score interactorA pp interactorB = 2.43 interactorX pp interactorY = 5.1 ...

Configured as part of each source's ProServer 2 INI file:

  [mysif]
  ... source configuration ...
  transport  = sif
  filename   = /data/interactions.sif
  attributes = /data/node-attribute.noa ; /data/edge-attributes.eda

  Retrieves interactions involving interactorA:
  $hInteractions = $oTransport->query('interactorA');

  Retrieves an interaction involving both interactorA and interactorB:
  $hInteractions = $oTransport->query('interactorA', 'interactorB');

  The returned hash is of the structure expected by ProServer.

  Generally not directly invoked, but if you really want to:

  $transport->DESTROY();

Run ProServer with the -debug flag.

The Simple Interaction Format is very simple, and therefore only supports a limited range of DAS annotation details. It also only handles binary interactions (i.e. those with exactly two interactors).

None reported.
