[gmx-users] position restraint

But the part in which the ions are introduced is #include "./charmm36-modified.ff/ions.itp" ,
Is this not the right place to write the posre_ion lines? As I see it is in agreement with "Atom index n in position_restraints out of bounds" link.
So what would be the solution? I don't see any itp file generated by pdb2gmx, for the ions such as chain A and other moleculetypes ?
Would you give me a hint and help me with it please?

I want to put position restraint on an ion ,
First made an .itp file of the ion: posre_ion.itp
Then added these line to top file:
And added the line to mdp file
define = -DPOSRES_ION
But the grompp failed because it gives me the fatal error that the
include line is not in the correct position.
Would you please let me know if the inclusion of posre_ion.itp is not
as I did? What's the problem?
Thanks in advance for your suggesions.
