Hi gromacs user I am simulating protein ionic liquid(IL) system, in my IL forcefield the function type of dihedral parameter is 5. When I am running gmx mdrun it appears the following error. Program: gmx mdrun, version 2018.1 Source file: src/gromacs/topology/topsort.cpp (line 139) Fatal er

[gmx-users] DSSP graph re-scale

2019-09-09 Thread SGR160055 Student
Dear experts, I have an issue to re-scale the x-axis on DSSP graph eps format for my 100 ns simulation time. The x-axis of the graph became too compact until it can't be read clearly. How should I solve this? Is there anyway to re-scale the graph for eps format. Your help is much appreciated. T

Dear All, I am facing an issue I do not fully understand. Namely, let's take two crystallographic structures of the same protein and in one of them let's delete three crystallographic water molecules that are not buried inside the protein (let's forget about a reason for it for a moment). Now, wh

dear all, I am trying to improve the GAFF2 dihedral parameters for a torsion on a small molecule. My small molecule has 5 torsions, only one is problematic, I have been able to improve the dihedral parameters for the other 4 torsions by adjusting the force constants of the GAFF2 dihedral terms. I

Hi, What does the log file detection output contain? You might have linked against a CUDA release not compatible with your drivers (e.g. too recent). Cheers, -- Szilárd On Sun, Sep 8, 2019 at 5:17 PM Mahmood Naderan wrote: > > Hi > With the following config command > cmake .. -DGMX_GPU=on -DCMA

Dear all, I am running REMD simulation with 65 replicas. When the simulation is running , I checked the .log file for every replica. In some replicas I am getting more than 10% load imbalancing. How to solve that. If I use -ntmpi and -ntomp option ..mdrun is throwing a fatal error Fat
