Hi,
GromPy is compatible with gmx 4.0.7. There are plans to port it to
higher gmx versions, but I do not know when that will happen.
Cheers,
René

Grompy looks like fancy.
Is it reliable for conducting GCMC??
I also need to perform GCMC along with MD.
In Grompy, it seems that the Grompy is compatible with gromacs 4.0.5.
The version of gromacs I use is 4.5.X.
Is it possible to use Grompy with my Gromacs??

Hi Renè,
This might be a silly question. In the documentation of GromPy it
says that:
"The system consists of mono-atomic water molceules defined in the
MARTINI force field. The intermolecular interactions between such
molecules are modelled using the Lennard-Jones potential only."
My system is all-atom and all-hydrogen and I need to use the GBSA
solvation model. Is it still going to work, or is the tutorial
just an example of what you can do with GromPy?
Thanks,
Gianluca

Hi Gianluca,
You might want to take a look at GromPy
(https://github.com/GromPy/GromPy).
This is a python interface to the GROMACS library.
Amongst other
applications, there is an option to perform
grand-canonical Monte Carlo
using GromPy. The necessary energy evaluations are
performed using direct
library calls to GROMACS. In this way it is possible to
get around the
possibly prohibitive file I/O in shell implementations
that use the
GROMACS executables. A paper on GromPy and GromPy/GCMC
has recently been
accepted in JCC, so more details will follow. In the
meantime you can
have a look at the code and the tutorial on the above
website.
Good luck!
Cheers,
Rene

Hi Gianluca,
I forgot to say that the step of compute the energies is
considered from
pdb2gmx until g_energy.
Sorry about my oblivion.

Hi Gianluca,
Thanks your question.
All steps to obtain a generation with 200 individuals, on
average,
is 6 minutes for 1VII, example. In each generation I must
converted my proteins Dihedral to Cartesian
representation, compute
the energies, choose the individuals which will go to
reproduction,
save previous population. This test was using one core of a
conventional Desktop computer.
The proteins, that I have tested my algorithm, vary from
20 to 56
amino acids.

Thanks Enrico!
Just wondering. How fast is it? Calling gromacs must have a
lot of overhead. Also, do you call mdrun or does g_energy
evaluate the energy?

Hi,
Although I don't work with MC simulation, I have
used Gromacs to obtain energies and others
protein features in my Evolutionary Algorithms
(EA).
In general lines, I created a script that calls
Gromacs programs and the output of these
programs, such as g_energy (I read its xvg file),
I stored it at a specific file which is
read by my algorithm and its values are put into
my data structure. I call Gromacs either
implicit or explicit solvent.
My project is working with EA until now. However,
the integration with GROMACS is able to
work with other kind of algorithms such as MC.
Actually, we have idea to work with MC. But,
I don't know when it will be possible. If you
want, we can talk about join these work.

Hi!
I would like to use gromacs to perform Monte
Carlo simulations in implicit
solvent of a protein near a surface. The
protein is treated as a rigid body
whereas the surface is fix.
I see that there are plans to code MC into
gromacs:
http://www.gromacs.org/Developer_Zone/Programming_Guide/Monte_Carlo
Is there a preliminary version?
If not, I wonder whether anybody has tried
to do MC with gromacs using IMD and
MDDriver:
http://www.baaden.ibpc.fr/projects/mddriver/
Besides this. Is there an easy way to obtain
the force field energy of a system
using gromacs? Would I have to run a 0-steps
MD and read out the energy? I know
that this would have a big overhead in a MC
simulation, but it might be worth
trying.
Thanks,
Gianluca
