Hi everyone,
I need the vdw parameters of two kind of metal ions: strontium and nickle.
I found that the value of some known metal ions in par_all27_prot_lipid.inp are quite different with the paratool reference paper. The reference paper is "UFF, a Full Periodic Table Force Field for Molecular Mechanics and Molecular Dynamics Simulations "
Is there any relationship between them?
Can I use the value in the reference paper for modulation?
any answer will be appreciated!
