[gmx-users] No addition of ions

Hi Gromacs users, Am running a MD simulation over a protein complex and before adding the ions. we run a grompp option then we get result as model net charge as some integer ie if +2.00. so we got to add 2 CL ions. But when i ran my protein for grompp it didnt give me any net charge so am not

There is no problem in being wrong. The problem is that he wants to be wrong. At least 4 different researchers gave constructive input and this subject keeps hitting the same key. I've always been told that worse than not knowing, is not wanting to know. Still, I apologize for my outburst. Best
