Re: [gmx-users] How can I maintain a distance of at least 0.5 nm from each other of solutes
Hi, Thanks for the replies. Since I want to increase distance among co-solvents with themselves and with solutes, i must firstly fill the co-solvents along solutes and solvents after that i remove solvent, finally by edittconf -translate the co-solvents uniformally is distributed in the appropriate distances. Is it OK? Rasoul On Sat, Apr 17, 2010 at 5:43 PM, Justin A. Lemkul jalem...@vt.edu wrote: Justin A. Lemkul wrote: rasoul nasiri wrote: Dear Justin, Hello again Thanks for the message.

Add solvent I don't fully grasp why the initial position of the co-solvents matters so precisely; you may have a hard time satisfying all of the simultaneous distance requirements. Everything is just going to diffuse around anyway during MD. Maybe you have some reason I'm not thinking of, but it's a potentially complicated problem to build. -Justin Rasoul On Sat, Apr 17, 2010 at 5:43 PM, Justin A.

Re: [gmx-users] How can I maintain a distance of at least 0.5 nm from each other of solutes
Thanks for the information. Because of haven't satisfactory model from my co-solvent and I have to add it randomly along with the solvent by genbox -ci -nmol. the reason of this criteria relate to crash of system (solute+co-solvent+solvent) in the first step of simulation, because small distance between solute and co-solvents and co-solvents with themselves cause to rise of pressure.
