Dear all,
We are proud to announce a CECAM tutorial on PLUMED.
PLUMED is an open source plugin for free-energy calculations in
molecular systems that can be interfaced, through a simple patch
procedure, with some of the most popular classical molecular dynamics
codes, including AMBER, GROMACS, NA

I wish G96 force fields had a similar website with so much useful
information.
It would be good if authors posted anything on the forum cause it's
completely empty right now.

Hi everyone,
Please I'm having a problem with mdrun:
If I type:
mdrun -v -s test.tpr -o test.trr -c test.pdb -x test.xtc -e test.edr -g
test.log
I never get the .xtc file. Can anyone tell me why & what can I do to have an
.xtc file?
Thank you
Carla

Dear gromacs users:
I have a couple of questions:
While doing auto correlation function under what condition i need

I finally figure out that the problem comes from the Coulomb 1-4

Hello everybody,
I tried to install gromacs 4.0.7 + openMM on Fedora core 10 x86_64, but I
had lots of problems with that.
I typed the configure options below to obtain a Makefile:

CPPFLAGS="-I/opt/openmm/include/openmm/ -I/opt/openmm/i

Dear all:
These days, I am trying to pull a slab of griphene moving along the Z direction
at a constant speed. The slab of griphene contains 700 atoms. After several

run. However, the run didn't produce the results which I

I am trying to run MD simulation over a docked complex (protein+ligand), to
confirm their dynamic stability in water media.
For the same I am using PRODRG server to generate topologies for ligand

Hi Vivek,
Either
1. Use the original ligand coordinates with the PRODRG topology
or
2. Fit the structure obtained from PRODRG to the original structure
