Dear all,
                 I am using the KEGGgraph package to construct metabolic
networks of various organisms and study their topological properties.My
query though is : Can the package KEGGgraph be used to construct a  weighted
directed graph in which the nodes are the pathways themselves and they are
connected if they share enzymes ? The no. of enzymes any two pathways share
can be used to give a  weight to the edge between the two pathways (nodes in
this case). Thanks in advance for any help.



Regards,

Anupam
