how to write pair coeffs if there are too many atom types

Dear Sir

I want to know whether the pair_coeffs can be written as one separate file then imported into the in file using commands like read_data.

Now I am using LAMMPS simulating DNA interactions with graphene. The DNA is all-atom model, leading too many atom types in the simulation. I have the parameters package including information about each atom’s potential parameters with others. Then can I use some certain commands to read the parameters into the in file? if not, could you please tell me another solution?

Best regards

See the include command. Anything you put in an
input script, can also be put in a separate file.
