Radial Distribution Function (RDF)

I need to know how we can use RDF results to find a system is fcc,bcc or hcp?
I mean if we have RDF vs distance diagram (calculated with compue rdf with LAMMPS).
Is there any specific criteria or something to find that?
Thanks

this is not a question about LAMMPS, so it is considered off-topic for this mailing list.
to see what an RDF for either of the crystal structures would look like, you can simple generate such a structure (with LAMMPS) and compute the RDF (for just one frame).

please note, that LAMMPS has several computes that use certain (documented) criteria to try to determine whether an atom is part of a certain crystal structure, which are likely more reliable than computing the RDF.
