thanks Java Fan, but can you show me how to work with the following example.

%graph = (
  'ARR1' => {'ARR1' => 1,'CHOP' => 1,'CIN5' => 1},
  'MET4' => {'cJun' => 1,'OASIS' => 1,'cMaf'=> 1,'cJun' => 1},
  'JunD' => {'OASIS' => 1,'MafK' => 1,'NFE2'=> 1,'p21SNFT' => 1},
  'MafB' => {'MafB' => 1,cMaf => 1},
  'MafG'=> {'MafG' => 1,'MafK' => 1,NFE2=> 1,'NFE2L1' => 1},
);

I have a graph like this with 57 unique protein(node) linked to a minimum of 1 which is linked to it self. these are samples of it. and note that each node has equal weight. which is 1

thanks again
