[gmx-users] Re: How to include sodium ion (Reply to Justin's mail)

The sodium ion I am talking about is part of the docusate sodium salt
(AOT). If I want to solvate 100 AOT molecules with water molecules, how do I
make sodium ions part of the system? I am not just adding sodium ions to
balance the charge of the system. The sodium ions are part of the AOT
molecules, so I need 100 sodium ions in the system. Do I just add one sodium
ion in the parameter file containing the rest of the 65 atoms of AOT, then
specify #include "ions.itp" in the fopology?
I appreciate your answers.
(Aside: Can you help with replying emails via this forum. I use gmail and
when I click the reply tab, it includes all the mails for that issue, and
there is no "subject" entry. So I always have to copy and paste the mail
before replying. I appreciate your help).

Shouldn't this be as simple as using genion and then:
in the topology? Or is there some other problem you're having?
