Dear all, I have just installed gromacs 4.6.5 in Cygwin build on Windows 7 platform. I want to test the installation but it keeps giving the error ./gmxtest.pl all ERROR: Can not find executable gmx pdb2gmx in your path. Please source GMXRC and try again. My Gromacs is installed in the C: drive

Dear All, I recentlly installed gromacs 5.0.1 and a few months later 5.0.4 (hoping there was adifference) as I am using terra grid with a 5.0.1 install. Now, I noticed 2 things, trjconv_d no matter what I do can not read or convert the .trr file, even with simple -f in.trr -o out.trr or

Hi Ming Use *-pbc mol* while using trjconv. Anyway it is not another box. Best Regards -- Tushar Ranjan Moharana B. Tech, NIT Warangal Ph D Student, CCMB, INDIA -- Gromacs Users mailing list * Please search the archive at http://www.gromacs.org/Support/Mailing_Lists/GMX-Users_List before

[gmx-users] periodic boundary conditions pbc=xyz

2015-04-05 Thread Ming Tang
Dear all, I did a simulation using periodic boundary conditions pbc=xyz. It turns out that the box is defined too small, and some atoms go to another box. Does this affect the simulation result? If not, how to display the real model (without separation) in VMD? Thanks in advance, Ming --

Hi Ming, You have another box in your (infinite) periodic system? Cheers, Tsjerk On Sun, Apr 5, 2015 at 10:32 AM, Ming Tang m21.t...@qut.edu.au wrote: Dear all, I did a simulation using periodic boundary conditions pbc=xyz. It turns out that the box is defined too small, and some atoms

Hi Tsjerk, I defined only one box. I mean several atoms in one chain run out of the boundary, and I can see them in the box but not in the chain. So I think maybe they run to the nearby box because of the periodic boundary conditions. Thanks, Ming -Original Message- From:

[gmx-users] simulating liquid SO2 (Sulphur dioxide)

2015-04-05 Thread Jashimuddin Ashraf
Dear gromacs users, I am trying to simulate liquid SO2 (Sulphur dioxide). So I tried to create an equilibrated structure of SO2 molecules using the gmx insert-molecules function. As I try to minimize the energy of the system, I always get this-
