If you mean that I need to modify the posre_ion.itp file to: ; position restraints for a_85563 of system
[ position_restraints ] ; i funct fcx fcy fcz 1 1 100000 100000 100000 It doesnt work.......... :-( Sincerely, Shima ----- Original Message ----- From: Mark Abraham <mark.j.abra...@gmail.com> To: Shima Arasteh <shima_arasteh2...@yahoo.com> Cc: Discussion list for GROMACS users <gmx-users@gromacs.org> Sent: Thursday, August 22, 2013 6:37 PM Subject: Re: [gmx-users] position restraint Now you have a [moleculetype] with one atom and hopefully a position restraint. But its [position_restraints] wants to act on atom 85563 of the molecule, which does not exist!
