During add ions steps using Gromacs
the overall charge on my protein was calculated qtot -35
So i have to add positive ions to neutralize the charge on protein.
then i have added 35 Na ions using command
but during the energy minimization steps i got warning for Na ions that
Warning: atom name 192746 in topol.top and 2HQA_modified_solv_ions.gro does not match (NA - Na)

What should I do ?
