[gmx-users] REMD

2019-07-30 Thread Bratin Kumar Das
Hi, I have some doubt regarding REMD simulation. 1. In the .mdp file of each replica is it necessary to keep the gen-temp constant? as example: 300 k is the lowest temp of REMD simulation. Is it necessary to keep the gen-temp=300 in each replica. 2. Is it necessary to provide -replex

Thanks Sir, I did like that only, Now how can I make the distribution plot for these vectors. Eventhough I used "gmx analyze -f .xvg -dist .." command. But results is not proper. Can you suggest me regarding this? Thank you On Tue, Jul 30, 2019, 17:27 David van der Spoel wrote: > Den

[gmx-users] clashes after energy minimization - Ser2 multiple copies

2019-07-30 Thread David de Sancho
Hi all I have been having trouble setting up a peptide+water simulation system due to the appearance of clashes in an energy minimization. Trying to pin down the origin of the problem I have found that a minimum system that reproduces my problem is a box with multiple copies of an unblocked

Hi all, First of all, thanks for all your valuable inputs!!. I tried Szilárd suggestion (multi simulations) with the following commands (using a single node): EXE="mpirun -np 4 gmx_mpi mdrun " cd $WORKDIR0 #$DO_PARALLEL $EXE -s 4q.tpr -deffnm 4q -dlb yes -resethway -multidir 1 2 3 4 And I

Kevin, Mark, thanks for sharing advices and experience. I am facing some strange behaviour trying to run with the two gpus: there are some combinations that "simply" make the system crash (the workstation turns off after few seconds of running); in particular the following runs: gmx mdrun -deffnm
