Re: [gmx-users] unusual trajectory

Group selection depends on what you want to see in the output trajectory. What I am trying to say is that per se nothing wrong seems to be happening -- you just have things crossing periodic boundaries. The messages about inconsistent shifts could also mean atom shifts across boundaries, which

Dear Alex, Which group I should select (system, CNT or lig)? After selecting each of them: There were 44 inconsistent shifts. Check your topology I'm confused. -- Gromacs Users mailing list * Please search the archive at http://www.gromacs.org/Support/Mailing_Lists/GMX-Users_List before post

Hi, CMake will link to whatever it is allowed to find. What does ldd on the executable report as the libraries being dynamically linked? Those are the ones that cmake found for which there were apparently no static equivalents. Mark On Sun, Jul 22, 2018, 18:16 Shayna Hilburg wrote: > Hi all, >

Hi all, I'm trying to install GROMACS 2018 for use on GPUs. We typically keep the software on the master node and just call it through a mounted drive on the compute nodes. However, despite using static library tags, it appears there are still dependencies. It works fine on our master node but not

Dear Mark, Thank you bery much for your reply. I do not know which tool is useful for the counting a time series of atom number. I think that gmx select is a possible one. However, I could not specify water molecules. If you have any experience of gmx select ... , please advise me on specifing wate

Hi, Your working directory is the one in which you are doing your work. You are making a copy of the normal force field folder, so that next time you use it, you know it is unchanged from what GROMACS provides. Having made the copy, edit the files in the copy. Mark On Sun, Jul 22, 2018, 09:49 工业
