Hi,
thx for reply. I don't understant what do you mean by "Store the 
coordinates in a pair of vertex attributes" (sorry i'm a newbie)
Here is what i want to do:

   FILE *gra;
   igraph_t graph;
   igraph_vector_t x,y;
   igraph_vector_init(&x, 1); igraph_vector_init(&y, 1);
  
   igraph_grg_game(&graph,size,0.3, 0,&x,&y);
     
   igraph_write_graph_graphml(&graph, gra);
  
   igraph_vector_destroy(&x);
   igraph_vector_destroy(&y);
   igraph_destroy(&graph);


   igraph_t graph_test;
   igraph_vector_t x_test,y_test;
  
   igraph_vector_init(&x_test, 1);
   igraph_vector_init(&y_test, 1);   
   igraph_read_graph_graphml(&graph_test, gra, 0);
  

So how can reload the 2 vector x_test and y_test ??
