[gmx-users] Adding hydrogen atom to specific Glu/Asp carboxyl oxygen atom

[Dawid das]

Dear Gromacs Experts,

I know how to specify which Glu/Asp residues are to be
protonated/deprotonated with
pdb2gmx tool. However, I do not like that the hydrogen is added to one of
the oxygen atoms
of carboxyl moiety. I would like it to be found on the other oxygen. Is
there any other way
except modifying the *top file by hand?

Best regards,
Dawid
