Hi!
You may want to try PLUMED, which is the evolution of grometa

and can do also steered MD and umbrella sampling.

[gmx-users] J-walking REMD

2010-01-27 Thread David Parcej

Dear All
Some time ago there was a discussion concerning the problems of REMD for 
large systems and the possibility of using the REST implementation of 
the method.
Mark, you mentioned that you had coded an implementation Okur  method 
(JCTC, 2006, 2, 420). How did it work and can you make this available?

Any other thoughts on REMD for large systems are also appreciated.

Why not use valgrind?
I switched from efence to valgrind a long time ago.
If you have a Mac it might be less effort to log into a linux machine

Hi Jochen,

it should work by putting it in the LDFLAGS. Either you should then
get an executable that says something like

Electric Fence 2.2.0 

at the very start of execution or it should not compile when
the library is not found.

Re: [gmx-users] Potential Energy

  I finally figure out that the problem comes from the Coulomb 1-4
 interactions defined by [pairs] part. When I remove this parts, the energy
 minimization ends with a big negative number. Thanks for your help.

 That's not a solution, that's a random number generator. Whether or not you
 need such pairs is force-field dependent. Ad hoc changes are ridiculous.
 Messing with force fields is an expert topic, and parameterizing a new
 molecule is difficult and risky.

[gmx-users] Questions about Pull Code

2010-01-27 Thread Jennifer Casey
Hello,

I am a new Gromacs user, and I could really use some clarification about the
pull code.  I am interested in creating the PMF for Na+ and I- in the
presence of THF.  I saw a previous posting that the best way to go about
creating the PMF is:
1)  Generate a trajectory of configurations along the reaction coordinate.
2)  Use the difference configurations as starting points for independent
simulations in sampling window.
3)  Use umbrella sampling to constrain in window.
4)  Use g_wham to construct PMF

This is how I am interpreting the instructions, but could you please let me
know if I am correct in my assumptions?  First I create a couple of unique
starting configurations, with Na+ and I- separated by specific distances.
Once that has been done, I take one such configuration and turn on the
options under com_pulling (especially pull_geometry = umbrella) in the .mdp
file.  I let this run for some amount of time, and end up with a pullx.xvg
and a pullf.xvg file.  I do this with the other configurations as well.
Once that has been done, I take all of these .xvg and .tpr files and create
a .dat file, which can be used with g_wham to construct the PMF.

I really appreciate the help.  Nobody in my lab has done this before, and I
am feeling pretty unsure of myself.

Thanks.

In general, yes, you've got the right procedure.  Coincidently, I have just 
created a PMF/umbrella sampling tutorial that is linked from the Tutorials 
page on the Gromacs site.  The system in the tutorial is certainly more 
complicated than what you're looking to do, but still might be of use.

Certainly not without more useful information - GROMACS version, 
simulation system size, actual command line. Even then, the best guess 
is probably that you're running genbox on a machine for which it wasn't 
compiled, or for which some shared libraries have been updated in an 
incompatible way. Try recompiling GROMACS if so.
