Hi,
Yes that command is right.
If you need to do other commands, the trjconv description and options are
in the second link I gave:

Berger parameters are united-atom and designed for use with GROMOS. I 
know some people have combined them with various protein force fields 
with varying success, but I would not do that. Berger parameters are 
wildly outdated and much better force fields exist. In your case, use 
Slipids, which are specifically designed to be compatible with AMBER.

Hello gromacs users,

To run 50 independent simulations, I would run minimization once and 
start from 50 new equilibration runs, each with a different set of 
initial velocities (change gen_seed or simply set to -1).


That approach may not be as robust as starting from 50 different 
configurations, but the exact approach depends on the system in question.

GROMACS is not well suited to rigid-body dynamics. Try software like LAMMPS.

Hi all
I have two questions:

1-  Is it correct to apply statistical ensemble NVT (N=constant,
T=constant) for simulating of carbon nanotube (as drug delivery)?  It
doesn’t leads to a pressure in the system that is far from normal pressure?
Some Author use VNT and the other use NPT. In the other word, when we can
use NVT ensemble to simulation CNT (as drug delivery)?


The ensemble should be chosen based on which conditions are relevant to 
the simulation. Perhaps some people use NVT simply to side-step any 
possibility of compression along the CNT axis; sometimes models are 
simplified in this way. Perhaps that's not the most accurate. That's 
your job to decide what is the best model for the questions you are 
trying to answer.



2-  How to distinguish between infinite CNT and finite CNT with command
in .mdp file?


The main difference is in the topology, but in the case of an infinite 
CNT, you must use "periodic_molecules = yes" in the .mdp file. Proper 
bonds must be specified in the topology.

Re: [gmx-users] Self-interaction across periodic boundaries

Thanks Mark.
The problem is that I would like to keep the overall concentration
constant, so, using a larger box e.g. with 2 times larger lateral box
dimensions,
needs me to increase the number of molecules 8 times, so even more likely
to lead to percolating structures in a larger simulation box.

Re: [gmx-users] how to visualize gromacs trajectory

2019-07-08 Thread sunyeping
Hello, steph,

I have read the workflow for trajectory fixing at 
http://www.gromacs.org/Documentation/Terminology/Periodic_Boundary_Conditions, 
but I don't know how to perform these steps.
The workflow reads:

First make your molecules whole if you want them whole.
Cluster your molecules/particles if you want them clustered.
If you want jumps removed, extract the first frame from the trajectory to use 
as  reference, and then use trjconv -pbc nojump with that first frame as 
reference
Center your system using some criterion. Doing so shifts the system, so don't 
use trjconv -pbc nojump after this step.
Perhaps put everything in some box with the other trjconv -pbc or -ur options.
Fit the resulting trajectory to some (other) reference structure (if desired), 
and don't use any PBC related option afterwards.
For the step 1, what this the command for keep the molecule whole? Should it be:
  gmx trjconv -s md_0_10.tpr -f md_0_10.xtc -o md_0_10_whole.xtc -pbc whole 
  ?
Could you give me some examples of the command for each step?

Thanks.

Hello,
It sounds like you have to fixed broken molecules and have problem with
boundary conditions.
After doing the MD, you need to fix your trajectory first before doing
visualization.
Check this link for a workflow:

Re: [gmx-users] Self-interaction across periodic boundaries

2019-07-08 Thread Mark Abraham
Hi,

If you're trying to model something like it was at infinite dilution using
a periodic box, then the size of the box needs to be at least as large as
the size of the structure and its effective interaction radius. It seems
like your simulation is suggesting at least one of those is larger than you
first thought it was :-)

[gmx-users] Self-interaction across periodic boundaries

2019-07-08 Thread Salman Zarrini
Dear all,
Using MD simulations I expect to observe aggregation among some molecules
solvated in water to have ultimately a droplet out of the molecules. The
aggregates form to some extent in the course of simulation time, however,
after a while the system become kinetically trapped in artificial
percolating aggregates in which the molecules are self-interacting across
the periodic boundaries.
I wonder if there is any possibility to prevent aggregates self-interaction
across periodic boundaries?

Thank you,
Salman

Subject: Re: [gmx-users] Install on Windows 10 with AMD GPU

Dear James,

Unfortunately, we have very little experience with OpenCL on Windows, so I am 
afraid I can not advise you on specifics. However, note that the only part of 
the former SDK that is needed is the OpenCL headers and loader libraries 
(libOpenCL) which is open source software that can be obtained from the 
standards body, KHronos. Not sure what the mechanism is for Windows, but for 
Linux these components are in packaged in the standard repositories of most 
distributions.

However, before going through a large effort of trying to get GROMACS running 
on Windows + AMD + OpenCL, you might want to consider evaluating the potential 
benefits of the hardware. As these cards are quite dated you might find that 
they do not provide enough performance benefit to warrant the effort required 
-- especially as, if you have a workstation with significant CPU resources, you 
might find that GROMACS runs nearly as fast or faster on the CPU only (that's 
because we have very efficient CPU SIMD code for all compute-intensive work).

To do a hopefully easier quick performance evaluation, you could simply boot a 
Linux distribution off of an external disk, you can find Linux drivers for them 
for Ubuntu 16.04/18.04 at least which you can install and see how well does the 
system perform.

I hope that helps!

Cheers,

Re: [gmx-users] About 2019 GMX manual

2019-07-08 Thread Paul bauer

Hello,

as Benson said, please open an issue at redmine.gromacs.org for all 
kinds of bugs that you find :) (even documentation issues like this)!
After this, you can upload a fix for the issue yourself at 
gerrit.gromacs.org after creating an account there, or one of us will 
get around to do this.


Cheers

Paul

Hi Alan,

This requires making a small change in the git repository at 
https://gerrit.gromacs.org


The relevant line is also mirrored at:

https://github.com/gromacs/gromacs/blob/master/docs/user-guide/system-preparation.rst 



but changes typically go through the git repository at 
gerrit.gromacs.org as indicated at:


http://manual.gromacs.org/documentation/current/dev-manual/overview.html#documentation-organization 



Can make the change on your behalf if it would be helpful.

Is there a better way to report issues with the current manual?

It's a very minor one, to update a link about ACPYPE on page 25.

To use: https://github.com/alanwilter/acpype

Thanks,
