[lammps-users] lattice and create_atoms using basis

It seems to be alright. But In your input file, there are several line breaks with lattice and create_atoms commands. Make sure to put "&"sign at each line break and don't put any spacing after "&" sign.

>>Is there a way for me to assign names to these atoms as say Ga and N?

I think the answer is NO. But does it make any difference?
