Dear All,
I am trying to prepare my protein in tleap. I loaded the protein, solvated
it with TIP3PBOX water type and now I am trying to neutralize the charge
with Na+ counter ions. But the added charges are in close vicinity of the
protein structure and I am afraid that it may affect simulation. I am using
following command for adding counter ions
*addIons var Na+ 0*

I also tried with addIons2 but in this case, only 4 Na+ are away from
protein but 8Na+ are still in close vicinity to the protein. Please let me
know how should i neutralize my system effectively.

Thanks and Regards,
Hirdesh Kumar
