Hello Mirzaei Total how many columns are present in the xvg file? Paste your data here, then we will know how to plot that. Thanks

[gmx-users] GROMACS Output Timestep Changes Over a Long, Check-pointed Simulation

2019-06-18 Thread Eric R Beyerle
Hi, I've run a fairly long (1 microsecond) trajectory of ubiquitin in spc/e on a supercomputer that allows a 48-hour runtime on their nodes. Since the simulation doesn't finish in 48 hours, I used the checkpoint files from the simulation to restart the simulation, using the following mdrun

Hi, Sorry, that's not great wording on our part, I'll fix it. As Eiso said, only simulations using the [ intermolecular_interactions ] are affected Mark On Tue., 18 Jun. 2019, 16:44 Eiso AB, wrote: > Hi Mateusz, > > The intermolecular interactions meant here are the one that can be >

Hi Mateusz, The intermolecular interactions meant here are the one that can be specifically defined as [ intermolecular_interactions ] in the topology (e.g. used to define distance restraints, between different molecules, see the manual). So you shouldn't have to worry about the general

Dear list, This has been discussed many times previously on the list, but I still have some questions about hydrogen bond autocorrelation functions. I have run a simulation with single molecule of a compound in water which can form exactly one inter-molecular hydrogen bond. From the hbnum.xvg

Dear Developers, I have read your latest release and I cannot work out how it affected my simulations. The overall description is very general and implies that all simulations done with 2019.0-2 should be discarded. If I understand correctly, most of the simulations run nowadays use domain
