Hey,

I tried concatenating those trajectory files in another machine (same
version: gromacs 5.1.4). It worked well without any error.

What is wrong with my own build?

[gmx-users] Length of a constrained bond

2018-04-17 Thread Eric Smoll
Hello Gromacs Users,

When setting "constraints=h-bonds" in an mdp file, what sets the
constrained bond length? Is it the equilibrium bond length in the topology,
the bond length deduced from the initial coordinates, or something else.

Best,
Eric

[gmx-users] simulation crash

2018-04-17 Thread Andrea Spitaleri

Hi there,

I am running several independent replica of similar system but in 
different pose of protein-peptide. I am in NVT ensemble and the length 
of the simulation is 125ns (dt=2fs). Few of them are crashing with the 
classic error:


"1 particles communicated to PME node 8 are more than 2/3 times the 
cut-off out of the domain decomposition cell of their charge group in 
dimension x.

This usually means that your system is not well equilibrated."

I am using 36 cores or a multiple of 36 (i.e. 72, 108, and so on). The 
weird things is that restarting the crashed replica from the checkpoint, 
it starts without problem and it goes for a while (hours). Then it 
crashes again and so on. I have checked the last frame before the crash 
and I do not see structural problem. Changing the number of cores from 1 
to 5 improves the things but not too much, it still crashes and 
restarts. IMHO, if there was a problem with the system the simulation 
should never restart, isn't?


any clue?

Hope I have been clear

Best

Andrea

[gmx-users] 3dc warning

2018-04-17 Thread Eric Smoll
Hello Gromacs users,

I am using version 2018.1.

I have a system in an infinite slab configuration (periodic in the x and y
dimensions; in the z dimension, the atoms are permanently confined to 1/3
of the unit cell length with the remainder vacuum).

I am interested in simulating the system with 3D PBC and PME. Since I am
only interested in the behavior of a single infinite slab, interactions
between images of the slab in the z-dimension are unwanted. The 3dc
correction seems like a useful way to increase the realism in my
simulations.

However, grompp generates a warning: "With PME and ewald_geometry = 3dc you
should use pbc = xy"

As I understand it, 3dc is a correction for periodicity in the z-dimension.
Is pbc=xyz inappropriate?

Best,
Eric

Re: [gmx-users] trjconv ndec not working

2018-04-17 Thread Paul Bauer

Hello Eric,

I had a look at the code for writing gro files and it looks to me that 
it is only able to write three decimal places there.
There is a comment in the code that mentions that writing other 
precisions has been removed.

This means that we need to update the man page text to not be confusing.

Cheers

Paul

Hello Gromacs Users,

I am using Gromacs 2018.1.

The manual page for gmx trjconv states the number of decimal places in the
output of a gro file is taken from the number of decimal places in the
input unless the ndec flag is set. The ndec flag can be used to increase
precision in the output.

However, providing trjconv a gro file with increased coordinate precision
(7 decimal places) does not increase the precision of the output gro file.
Also, the ndec flag has no impact on the output precision.

My input gro is written as follows:

trconv does not complain about this file format and creates a normal, three

gro file as output.

Has this feature been removed?

That's precisely your problem. The CGenFF server is using an old
version, and therefore it finds bonded parameters that need to be
guessed by analogy. In fact, CGenFF 4.0 has these parameters and they
are the values you should use. So for all of the parameters that are
being overridden, remove them from your .prm file before #including it
in the topology. The optimized parameters in CGenFF 4.0 are what you
want, and they're all already there in ffbonded.itp.

Okay thanks, this is what I did. I just was not sure wether the approach was 
appropriate.



I wanted now to check if the parameters exist in the CGenFF for CHARMM and they 
don?t!

I'm finding them. It's impossible for grompp to say something is in
ffbonded.itp if it isn't. Be sure you're considering forward and reverse
orders of atom types when you're searching for them.

Yes, sure you find them in the charmm36-jul2017.ff/ffbonded.itp, but they are 
missing in the CGenFF version for CHARMM the 
toppar_c36_jul17/par_all36_cgenff.prm file (both the latest release). So why is 
there a discrepancy, or is it even a discrepancy or rather something I am 
missing here?



The GROMACS files come directly from the CHARMM files via a Python 
script. There's no secret magic. If it's in GROMACS, it's in CHARMM. 
You're either looking in the wrong place or you're trying to match the 
wrong string.

How is it possible that the parameters exist in the Gromacs version of CHARMM force-field

Why are the dihedrals considered duplicate, when the atomtypes clearly are

Yes, sure you find them in the charmm36-jul2017.ff/ffbonded.itp, but they are

Hi,

That looks like a broken build of GROMACS, rather than a bug in the code or
a broken file. Can you try those gmx check commands on another installation
somewhere else? (Also gmx check -m doesn't do anything useful any more, so
don't buy trouble by using it!)

Re: [gmx-users] CGenff parameters in gromacs but missing in charmm package

2018-04-17 Thread Justin Lemkul



On 4/17/18 3:34 AM, Fabian Keller wrote:

Dear all,
I am using the CGenFF/paramchem framework for a new molecule (an imidazolium 
cation derivative with methyl groups on both N atoms).
I faced a known problem going from CHARMM package to Gromacs with parameters 
already existing in CHARMM for Gromacs. I assume that this is due to paramchem 
only being implemented for CGenFF3.0.1 and Gromacs using version 4.1.


That's precisely your problem. The CGenFF server is using an old 
version, and therefore it finds bonded parameters that need to be 
guessed by analogy. In fact, CGenFF 4.0 has these parameters and they 
are the values you should use. So for all of the parameters that are 
being overridden, remove them from your .prm file before #including it 
in the topology. The optimized parameters in CGenFF 4.0 are what you 
want, and they're all already there in ffbonded.itp.



I wanted now to check if the parameters exist in the CGenFF for CHARMM and they 
don’t!


I'm finding them. It's impossible for grompp to say something is in 
ffbonded.itp if it isn't. Be sure you're considering forward and reverse 
orders of atom types when you're searching for them.


-Justin


How is it possible that the parameters exist in the Gromacs version of CHARMM force-field 
(http://mackerell.umaryland.edu/download.php?filename=CHARMM_ff_params_files/charmm36-jul2017.ff.tgz
 
)
 while they are missing in the CHARMM FF version 
(http://mackerell.umaryland.edu/download.php?filename=CHARMM_ff_params_files/toppar_c36_jul17.tgz
 
)?
Why are the dihedrals considered duplicate, when the atomtypes clearly are 
different? Is this due to CHARMM handling dihedral potentials differently to 
Gromacs?

Following the link you find all used parameter and force field files 
(https://www.dropbox.com/sh/m89q64g0pae6wrf/AAAx1aNtJ1TZKNDFgUo2oSu7a?dl=0 
) 
and in the following the error output.
Thank you very much for all hints and help!
Best wishes,
Fabian

Hi,

I meant to run

gmx check -f 100cat.xtc

gmx check -f new2.xtc

on the separate files, to find out e.g. whether they are trajectories that
have matching numbers of particles, etc.

[gmx-users] Issues using Implicit Solvent with Charmm 27

2018-04-17 Thread Juan José Galano Frutos
Hi there,

I am trying to simulate a protein using a GBSA (implicit solvent) approach,
and first I've been googling a bit in order to set the parameters of the
simulation (mdp file) as better as possible.

I am using the following mdp options for the minimization step (the
parameters of the Implicit Solvent section are also set in the subsequent
NVT and NPT steps):

title   = Energy Minimization   ; Title of run

; The following line tell the program the standard locations where to find
certain files
cpp = /lib/cpp  ; Preprocessor

; Define can be used to control processes
define  =
cutoff_scheme   = group

; Parameters describing what to do, when to stop and what to save
integrator  = steep
emtol   = 1.0
emstep  = 0.01
dt  = 0.001
nsteps  = 4
nstenergy   = 500
energygrps  = System

; Parameters describing how to find the neighbors of each atom and how to
calculate the interactions
ns_type = simple
coulombtype = cut-off
rcoulomb= 0
vdwtype = cut-off
rvdw= 0
constraints = none
pbc = no
ld-seed = 1
nstlist = 0
rlist   = 0
comm-mode   = angular
comm-grps   = Protein
optimize_fft= yes

; Implicit solvent

implicit_solvent = GBSA
gb_algorithm = OBC
gb_obc_alpha = 1
gb_obc_beta  = 0.8
gb_obc_gamma = 4.85
gb_dielectric_offset = 0.009
nstgbradii   = 1
rgbradii = 0
gb_epsilon_solvent   = 80
gb_saltconc  = 0
sa_algorithm = ace-approximation
--

The point is that after this minimization step I am obtaining a protein
where the alpha helixes seem to be something relaxed or extended in an
unusual way at least compared to when explicit solvent is used. This fact,
i.e. such a local structural weakening, lead then to a fast protein
unfolding during the subsequent NVT and NPT steps something that I am sure
is not normal that soon.
So, my question is whether there is someone over there has performed
simulations combining CHARMM27 force field and a GBSA approach and has
happened the same? Is there any incompatibility between them using GROMACS?
I could find some papers in which this combination is used but using NAMD.
Any help or advise would be appreciated so much.

Thank you!!

Hey Mark,

Thanks for the reply. I did gmx check on both the .xtc files. Now,
even this command is yielding the same error.

My command: gmx check -f 100cat.xtc -f2 new2.xtc -m report.tex

Hi,

No, CUDA is a toolkit for compiling and running on GPUs. A compiler is a
program for turning source code into something a computer can run. Your OS
seems quite old, so the default compiler is too old to be useful for
compiling GROMACS. How to decide what to do to get an updated compiler is
not really on topic here, because it's so specific to your OS.

Thank you so much for your quick reply.
"you will need to use a more recent compiler"
for my installation error i did not understand about "CUDA".
Did i need to install cuda to overcome the error.

Hi,

What does gmx check report on the two input .xtc files?

Re: [gmx-users] installion of gromacs 5.07

2018-04-17 Thread Mark Abraham
Hi,

Please consider installing a recent version of GROMACS, which is not only
easier to use and install but is still supported and will have fewer bugs,
too. Either way, you will need to use a more recent compiler than you seem
to have available on your system.

Mark

[gmx-users] Error in gmx trjcat

2018-04-17 Thread Syed Azeem
Hey all,

I'm experiencing an error while using trjcat command. Initially, I ran
a simulation for 50 ns and then extended till 100ns. After extension,
I concatenated the trajectories of both the runs using gmx trjcat.

Then, again I extended the run from 100 ns to 500 ns. Finally, I tried
to concatenate the previously concatenated 100 ns trajectory file with
the final (500 ns) trajectory. This step yielded an error (pasted
below).

GROMACS:  gmx trjcat, VERSION 5.1.4

Dear all,
I am trying to do md simulation of protein in osmolyte. When I run the full
md, the simulation stops after 9 ps with lots of step.pdb file. No error
appears in .log file but simulation stop.  will anyone please tell me what
should I do as I am unable to understand the error. Also no error appears

[gmx-users] Installation of g_mmpbsa with Gromacs 2016.3

2018-04-17 Thread Hermann, Johannes

Dear Gromacs-Users,

I know that g_mmpbsa is not a Gromacs tool but I guess there are some 
people here who installed / used it.
I want to install g_mmpbsa using my current 2016.3 gromacs gmx_mpi 
installation and my already installed apbs 1.4.1.
First of all, in the installation instruction of g_mmpbsa it says, that 
gromacs 4.6.x should be installed with -DGMX_GPU=off. Will it work with 
my 2016.3 version, where I use gpu acceleration?
Has anyone a similar configuration and tried installation of g_mmpbsa 
the following way:


cd g_mmpbsa
mkdir build
cd build
cmake -DGMX_PATH= PATH/TO/GROMACS \
  -DAPBS14=on \
  -DAPBS_INSTALL=PATH/TO/APBS \
  -DCMAKE_INSTALL_PREFIX=/opt/g_mmpbsa \
  ..
make
sudo make install


Thank you very much in advance for your help!

All the best
Johannes

[gmx-users] CGenff parameters in gromacs but missing in charmm package

2018-04-17 Thread Fabian Keller
Dear all,
I am using the CGenFF/paramchem framework for a new molecule (an imidazolium 
cation derivative with methyl groups on both N atoms). 
I faced a known problem going from CHARMM package to Gromacs with parameters 
already existing in CHARMM for Gromacs. I assume that this is due to paramchem 
only being implemented for CGenFF3.0.1 and Gromacs using version 4.1.
I wanted now to check if the parameters exist in the CGenFF for CHARMM and they 
don’t!

How is it possible that the parameters exist in the Gromacs version of CHARMM 
force-field 
(http://mackerell.umaryland.edu/download.php?filename=CHARMM_ff_params_files/charmm36-jul2017.ff.tgz)
 while they are missing in the CHARMM FF version 
(http://mackerell.umaryland.edu/download.php?filename=CHARMM_ff_params_files/toppar_c36_jul17.tgz)?
Why are the dihedrals considered duplicate, when the atomtypes clearly are 
different? Is this due to CHARMM handling dihedral potentials differently to 
Gromacs?

Following the link you find all used parameter and force field files 
(https://www.dropbox.com/sh/m89q64g0pae6wrf/AAAx1aNtJ1TZKNDFgUo2oSu7a?dl=0) and 
in the following the error output.
Thank you very much for all hints and help!
Best wishes,
Fabian

Sure. But first you should understand why the number of degrees of freedom
in the system are relevant for affecting the temperature spacing required
for constant exchange probability. See, among other references
https://pubs.acs.org/doi/abs/10.1021/ct800016r (shameless self-plug...)

What results are you seeking? Why would the number of replicas be a
relevant parameter determining the result?

[gmx-users] Fwd: REMD Simulation

2018-04-17 Thread ISHRAT JAHAN
Dear all,
I am trying to do REMD simulation in different cosolvents. I have generated
temperatures using temperature genrating tools but it gives different
number of temperatures in different solvents with exchange probability of
0.25. Is it fair to do remd with different replicas? In what way it will
effect the results?
Thankyou
