[gmx-users] mpi segmentation error in continuation of REMD simulation with gromacs 4.5.5

Dear all, I'm trying to continue a REMD simulation using gromacs4.5.5 under NPT ensemble, and I got the following errors when I tried to use 2 cores per replica: "[node-ib-4.local:mpi_rank_25][error_sighandler] Caught error: Segmentation fault (signal 11) [node-ib-13.local:mpi_rank_63][error_sigh

[gmx-users] Question about Extention simulation in REMD

Dear Sir or Madam, I wonder how to continue a REMD running using .cpt file in Gromacs 4.5.1. Since I ran a REMD of 56 replicas, there are one cpt file for each replica.. I couldn't do it by tpbconv -s previous.tpr -extend timetoextendby -o next.tpr mdrun -s next.tpr -cpi previous.cpt I guess it

whether there's some problem and what caused it.. My setting In the .mdp of the previous simulation, gen_vel was on; I didn't record the velocity by putting nstvout =0; I used xtcgrp = Protein. Best Qin 2010/12/15 Justin A. Lemkul > > > Qin Qiao wrote: > >> Dear Sir

Thanks! It really is. For the input cpt may have been overwritten before, when I put it in mdrun again.. 2010/12/17 Mark Abraham > > > On 12/17/10, *Qin Qiao * wrote: > > Thanks! > > But still sth strange: I found the total energy is not identical between > the last fr

[gmx-users] Nose-hoover T-coupling nsttcouple

Dear all, I wonder what will happen in Nose-hoover coupling when tau_t = dt * nsttcouple, while nsttcouple = nstlist. (I used -maxwarn 1 to ignore the Gromacs warning) I tried this setting, to find the temperature is OK, but I am not sure whether it will introduce some artifacts in the simulation

Re: [gmx-users] Nose-hoover T-coupling in REMD

Thanks a lot! It says Nose-hoover coupling generates the correct canonical ensemble, and that's the reason why I used it. I wonder whether v-rescale can also get the correct ensemble. Could you tell me? I'm quite curious how to choose the frequency of the T-coupling in REMD. Though it seems the h

Re: [gmx-users] Nose-hoover T-coupling in REMD

I'm not sure, since actually kinetic energy should have fluctuation, and the v-rescaling may suppress the fluctuation.. 2010/12/25 ms > On 25/12/10 02:12, Qin Qiao wrote: > >> Thanks a lot! >> >> It says Nose-hoover coupling generates the correct canonical ensemble,

[gmx-users] To make continuous trj in REMD

Dear all, I came across a problem when I want to make the REMD trajectories continuous. What I did: 1. 'demux.pl REMD_0.log' --to get the 'replica_index.xvg' 2. 'trjcat -f ../REMD_*.xtc -o resort.xtc -demux ../replica_index.xvg' It seems smooth. But when I check the rmsd of the output
