[gmx-users] vdwradii issue

2016-04-21 Thread badamkhatan togoldor
Dear Gmx-Users
Currently i'm having this kind of sticky warning when i am doing gmx solvate or 
gmx editconf (ff was charmm and oplsa). However i copied vdwradii.dat in my 
working directory, or use -vdwread flag still get this warning..Please how to 
get rid off of this Warning!

This means the results may be differentcompared to previous GROMACS versions.
Please give a some help! Thanks. (Im using gromacs/5.1.1 version)

Re: [gmx-users] gmx convert-tpr, gmx check Q ?

2016-04-12 Thread badamkhatan togoldor
Thank you for reply of Justin. So as I understood from there no need to 
convert-tpr and just do it like,
 gmx mdrun -deffnm pro$ -cpi pro1.cpt  -append 
That's it ?

There is no need to invoke convert-tpr for a run that stopped prematurely.

The timestep here (in ps, as noted) is the interval between frames.

What does gmx check tell you about the contents of each of these?  The help 
info 
for mdrun also explains the checkpointing mechanism and the difference in these 
files, so start by reading that.

[gmx-users] do_dssp problem

2016-03-22 Thread badamkhatan togoldor
Dear Gmx-Users,
I had done roughly 300ns peptide and membrane simulation. I am trying to do 
some analyses through the do_dssp. To get in .xpm file I put .xtc and .tpr 
files. Then at certain frame its just killed and gave me the empty files with 
strange names like ddccTf1j, ddmMD9pt, ddmuWFKIin this case what should i 
do? reduce the reading frame number (300.000 frames)? or is it cluster related 
issue? Any advices and helps will be highly appreciated !         
Regads, 
Khatnaa

[gmx-users] Note of geometric combination rules in LJ-PME

Dear GmxUsers,



Recently I got this Note in my enegy minimization (l-bfgs) step. I am using 
5.1.1 version. 
  You are using geometric combination rules in LJ-PME, but your non-bonded  C6 
parameters do not follow these rules. This will introduce very small  errors in 
the forces and energies in your simulations. Dispersion  correction will 
correct total energy and/or pressure for isotropic  systems, but not forces or 
surface tensions.
Here is my part of em_l-bfgs.mdp option.

Given the two-body interaction length, your .mdp file probably specifies 
couple-intramol = no, which generates explicit pairs and exclusions for 
intramolecular interactions, thus driving up the minimum size of a DD cell 
considerably.  So your system is incompatible with more than a few DD cells.

The better question is why you're trying to decouple an entire protein; that is 
extremely impractical and unlikely to be useful.

[gmx-users] grompp

2015-10-15 Thread badamkhatan togoldor
 Dear Gmx Users, 
I have a question on grompp ! 
I built some membrane in Charmm-gui with ion and water etc and i took that 
output data for gromacs. Then i changed .pdb file on the gromacs. Do the 
pdb2gmx and editconf then grompp. Unfortunately grompp gave me an error!
No default U-B types.[file topol.top, line ] 
In this case what should i do?( I thought charmm-gui generated and supplied all 
ffbonded.itp ( .itp files was in "toppor" directory ) file for this membrane. 
and then i should put it that file on gromacs' ffbonded. itp file ? ) What's 
the wrong in here? Any help or suggestion highly appreciate!       I am using 
charmm36.ff . 
Thank you!  Khatnaa

[gmx-users] Peptide, lipid simulation

2015-10-01 Thread badamkhatan togoldor
Dear Gromacs Users,I would like to use g_membed to insert my peptide into 
membrane. But I got this errors and notes in grompp
ERROR 1 [file membed.mdp]:
  Energy group exclusions are not (yet) implemented for the Verlet scheme

NOTE 4 [file membed.mdp]:
  NVE simulation with an initial temperature of zero: will use a Verlet
  buffer of 10%. Check your energy drift!

NOTE 5 [file membed.mdp]:
  You are using a plain Coulomb cut-off, which might produce artifacts.
  You might want to consider using PME electrostatics.membed.mdp file include 
following options: integrator      = md
energygrps        = Protein
freezegrps         = protein
freezedim          = Y Y Y
energygrp_excl   = protein protein
nsteps           = 1000
So I don't know I have to put more options? or use other .mdp file? If someone 
have appropriate .mdp file, please share !

[gmx-users] peptide lipid simulation

2015-09-24 Thread badamkhatan togoldor
Hi,i’m following KALP-15 in DPPC tut in my own peptide (novel) and lipid 
(pope). I created charm27_lipid.ff for my lipid. In this case i should create 
for such ff to my lipid or it’s necessary to create? Then its gave me fatal 
error on grumpTopology include file "gb.itp" not foundWhere i have to put this 
file? Any help and suggestion highly appreciate! Badamkhatan Tuguldur
