[gmx-users] mpi run in Gromacs

Hi, I am a Phd student studying polymer membranes. I have installed Gromacs version 4.5.2 on our department cluster and attempted to run a simulations on a DPPC bilayer membranes taken from the tielleman website. I have set the system up in an NPT ensemble using a semi-isotropic pressure

[gmx-users] water residence time on a certain group of ligand

Dear gromacs users, I want to calculate water molecules residence time on a certain groups of a ligand. I found in gromacs exercises how to do it: https://extras.csc.fi/chem/courses/gmx2004/exercises/index.html To get water residence time I need: 1) Obtain hbac.xvg, using this command: g_hbond

[gmx-users] Particle type 'B' in topology file?

Hi all, I have performed a simulation where for an atomtype, I accidentally put 'B' instead of 'A' which stands for 'atom'. The manual doesn't mention any 'B''s for particle type, (it mentions A,S,V and D). I have then corrected this (replaced B with A) and obtained a totally different

Re: [gmx-users] oplsaa galactose

Hi, I am trying to simulate hexopyronase using OPLS-AA forcefield using parameters from the paper: An improved OPLS?AA force field for carbohydrates, 2002 by Gunsteren. The set of torsional angle parameters in the paper are given in Kcal/mol, but because I am using OPLS-AA I would need
