[gmx-users] a box of water

2012-09-07 Thread Turgay Cakmak
Hi all, I want to do Molecular dynamics simulation of a box of water (SPC type). I get the spc216.pdb file from the gromacs/share/tutor. Firstly, I did geometry optimization for nsteps= 5. Now, can I continue with production run or do I need to do equilibration runs to arrive correct

[gmx-users] from GMX to NAMD/Amber

2012-09-07 Thread Steven Neumann
Dear All, I want to use ACEMD software on GPUs which I have an access to. It could take while before I would prepare system of interest in NAMD or Amber Tool as I always used Gromacs. Do you know whether there is an easy way to translate gro/pdb files (equilibrated) and topology prepared in

[gmx-users] Energies in simulation and rerun using different core counts

2012-09-07 Thread Richard Broadbent
Dear All, I've been having some issues with energies with gromacs running on various core counts for a 7469 polymer in solvent system, constraining all bonds and running with a 2fs time step. I used PME-shift (1.05nm, 1.10nm), and a shift with the same parameters for the VdW, I am using the
