Can the shapefile dielectric numbering be useful in identifying composition assignment for the layers? For example, for the simulations I've been running involving two dielectrics for a nanoshell composed of a shell and a core, there are two numbers in the shapefile that are generated which are assigned to coordinates of dipoles based on  where they are - in the core or shell. 

Looking at the coordinates and the numbering - I concluded that the shell should be assigned the composition 1 dielectric while the the core the composition 2 dielectric. Can you verify that this is the case?
