Re: [gmx-users] script
You could use a sed command in your script to replace that line, something like sed "s/original expression/new expression/" filename -i But it depends a lot on how your mdp file is formatted in terms of spaces and tabs.

It is fine. My question was not about '.mdp' itself. I meant how to define the 'Temperature' inside the bash scrip, to avoid changing it by opening the .mdp file.

[gmx-users] VMD visualization is failed
Dear all I have simulated a protein-ligand system and the md.xtc and md.gro are now generated in the output. Unlike my previous simulations of nano systems in which the .trr trajectory was in the output and the visualization could be done in an straight forward way of opening the .gro and .trr consecutively, the .trr is not present now. I used gmx_mpi -f md.mdp -c npt.gro -t npt.cpt -p topol.top -n index.ndx -o md.tpr AND gmx_mpi mdrun -ntomp 2 -pin auto -s md.tpr -cpi md.cpt -tunepme -v -gpu_id 0 -nb gpu AND also gmx_mpi trjconv -f md.xtc -s md.tpr -o md_convert.gro -ur compact -pbc mol -center. How should I visualize the simulation in VMD having the .gro and .xtc?Is there a problem in the commands I used or a missing option in the .mdp that the .trr is not generated?Thanks. -- Gromacs Users mailing list * Please search the archive at http://www.gromacs.org/Support/Mailing_Lists/GMX-Users_List before posting! * Can't post?

[gmx-users] User tabulated potential and VdW Modifier
Dear everyone, My question concerns the effect of the mdp option "vdw-modifier" when vdwtype is set to user. I have a tabulated 8 - 6 Mie potential and I'm simulating a coarse grained water, NaCl system, which all interact with the same potential form but different dispersion coefficients. I wanted to check the energy conservation of that system and therefore set up a simulation as follows: dt = 0.008 cutoff-scheme = group rlist = 2.3 vdwtype = user vdw-modifier = potential-shift rvdw = 2 rvdw-switch = 2 coulomtype = PME-switch rcoulomb = 2 rcoulomb-switch = 1.95 I will limit my discussion to the VdW energies, since I trust the PME algorithm and I did not change any of the settings in the following discussion. As far as I can judge, this system should be energy conserving, because the potential is shifted, and there is enough space between rvdw and rlist to allow for diffusion in between updates of the neighbourlist. However, this system exhibits an energy drift (total energy) of over 1000 kJ/mol over the course of 30.000 integration steps. On a side note, I also calculated the LJ long range corrections, which is -1888 kJ/mol. After this simulation I thought, that the vdw-modifier does not affect the tabulated potential. Therefore, I calculated a shifted version of my potential and fed it to gromacs with the same parameters except: vdw-modifier = none which effectively should enforce a cutoff equal to that in my tabulated potential (2nm). This setup conserves the energy (Drift ~ 0.4 kJ/mol) and gives me a slightly higher LJ energy, which I expected. However, the long range correction was different: -946 kJ/mol (appr. half). This seemed odd to me, so I played around with some settings and found that the LR correction took the value of -946 for vdw-modifier = none and -1888 for vdw-modifier = potential-shift. This was also true for a setup with rlist = rvdw = rvdw-switch = 2 (and nstlist = 1), so it wasn't the difference between rlist and rvdw-switch. According to the manual and grompp notes, the LR correction is calculated as -C6/r_c^6, which should be the same for all simulations, but apparently the vdw-modifier changes something somewhere. Does anyone have an explanation on what's the reason for the behaviour of the LR correction? And also, more generally, are vdw modifier supposed to work for user lists (and if so, why did my initial setup not work)?

[gmx-users] question about the QM/MM calcuation in Gromacs/ORCA interface
Dear all, I am going to use Gromacs/ORCA interface for QM/MM calculation in the metalloenzyme model. I have done some QMMM calculations with other interface (AMBER/TURBOMOLE) I am also familiar with QM in ORCA but new user of Gromacs! I could get general overview how this feature works in Gromacs (from 2 provided tutorial examples and also Q/A of users in the mailing list) but that would be great to have a successful sample model to reproduce data before running the real model. I was going to test "Thymine dimer splitting" as given example with MOPAC interface (http://wwwuser.gwdg.de/~ggroenh/SaoCarlos2008/html/tutorial.html) and using provided files from the website then use ORCA interface for QM part but it was not successful. so can you please someone share the example with me (inputs/output). Any help would be really appreciated!

[gmx-users] v-rescale reproducible restart
Dear gmx comunity, I have done the following: -Ran a 100ps simulation and then starting with the same conditions a 30ps simulation and then restarted upto 100ps. -If I use -reprod and Nosé hoover thermostat in both trajectories the final structures match. -If I use v-rescale it doesn't. I know since v-rescale is stocastic, random numbers should be properly saved in the cpt for the chain of random numbers to be reproducible when doing a restart. I am not sure if this is not happening because it is impossible to do or if it is a bug. If it is not a bug, a note or something in this regard in the output would be nice. I am using gromacs.2018.4 with mpi. In addition, I think the name of the thermostat "v-rescale" is not very good (although I am not sure if it's too late to be changed). It gives the impression that velocities are just being rescaled (which would be completely wrong). Furthermore, if we credit with the author name the Parrinello-Rahman, Nose-Hoover, Berendsen methods. Why not Bussi-Donaio-Parrinello? Thank you very much!
