4.6.7 won't let me use SHAKE with reaction field and pressure coupling, which is why I am now using LINCS. Thanks, Cara > From: mark.j.abra...@gmail.com > Date: Thu, 2 Jul 2015 10:42:23 + > To: gmx-us...@gromacs.org > Subject: Re: [gmx-users] LINCS warnings for a single

Hi, While we can't exclude the possibility of a code bug, your analysis and results suggest the problem lies elsewhere. Is the EG model stable if you e.g. put one in a box of decane? It's a stab in the dark, but if EG was parameterized only for aqueous-phase properties, then all bets are off once

Hi everyone, I am trying to run a simulation of a lipid bilayer with a multi-component solution. One of the components is ethylene glycol. Some of the components have a tendency to wriggle their way into the lipids. When an EG molecule does this, it tends to get uncomfortable and trigger some L
