[igraph] intersect graphs sharing a percentage of edges and vertices

[jfertaj]

Dear list,

 have a list of graphs (igraph format) and I would like to obtain a merge graph, which would be the intersection of those nodes and vertices that are shared a certain percentage trough all the graphs.

I know that igraph library has the function graph.intersection() but this function intersect all the vertices and nodes present in all the graphs.

Any help would be much appreciated
