Hi, Sir,

Thank you very much for your prompt reply.

Unfortunately I failed to find something pertinent to my problem above there (maybe I missed it, though).

Like what I did in LAMMPS, I simply set parameters for si-si-si interaction in SiO-tersoff to zero, then I get no double-counting for Si interaction, and only Si-sw works for it. I just want to do the same thing here in QW otherwise I get double-counting.
