DPLR: setting of parameter sel_type

[ghost]

I am trying to use the DPLR model in the ionic solution, which contains H, B, C, F and N. In the beginning, DW model is trained first with parameter type:dipole. Since there are many element in the system, I would like to know how to specify the list of parameter sel_type, and how to specify which is which, e.g. bond type 1 between atom F and N, bond type 2 between H and N, etc.

no bond needs to be specified between real atoms.

Thank you for your reply.

I see. So, in such a case, if the sel_type is left unset, there should be 10 types of interaction (according to 2-combination of 5 elemens), and I have to set the list of model_charge_map as corresponding to the same number of sel_type.

Is that true?
