Dear Prof. Julian
I was working with the " hNN_WenTadmor_2019Grx_C__MO_421038499185_001" potential for the bilayer graphene (AB stacked structure) in order to produce eigenvectors and the dynamical_matrix.
Somehow on running the GULP with KIM I am finding the error
"ERROR : Finite difference phonons only allowed for gamma point"
Could you please tell me as to why such an error is occuring ?
