Dear All,
        I want to plot the phonon spectrum of graphene-BN  structure, but there 
are some warnings for Gamma calculations:

                   NOTE: orbital pair      1   952 (at least) is multiply 
connected.
                   NOTE: Harmless for Gamma calculations, except if a COHP 
analysis is intended.
 
       I wanna konw what this means.
 
Best Regards
 
LIU
