Hi Vaishali,
personally I am using cy3sbml to map metabolomics and proteomics data on metabolic networks.
http://apps.cytoscape.org/apps/cy3sbmlThis is more of a targeted approach where you know your pathways
(which you can encode in SBML via species, reactions and proteins as catalysts)
and than map data on the network.
Hope this helps.
Best M
