Dear LAMMPS users, I need to build a molecule having a virtual atoms for the lone pair on the specific atoms. I made lammps data file and ran simulation. But it crashes at the beginning of the simulation. The error message says “Cannot compute PPPM”. I think this is because…

First of all, I’m very new to LAMMPS so I’m sorry if my question is trivial.I’m trying to model a gas of atoms that float in a square box, they obey an NVE integration and only feel a shifted Lennard-Jones potential, no other interaction is introduced. What I’m trying to…

Dear all, I hope you feel great. I have two questions: 1- I pyrolysis a box consisting of 10 chains of polymer, and for this purpose, I used the Reax-FF. After pyrolysis, I want to know which molecules and how many of them are produced. Could you please suggest tools…

Has anybody used RIP-MD tool for generation of RIN from MD trajectories? 0 I have been trying to use the RIP-MD tool for generating residue interaction networks from pdb file and MD trajectories. I have tried installing the VMD plugin and running the files through that for the same. But…

Extracting coordinates of possibly H bonded solvent molecule using BioPython 0 Hi, I am trying to extract the coordinates of solvent molecule from a peptide PDB, within a distance of 3 ang of O and N atoms in peptide. Using VMD, I can extract up to 3 ang of peptide….

This directory contains libraries that can be linked to when building LAMMPS, if particular packages are included in the LAMMPS build. Most of these directories contain code for the library; some contain a Makefile.lammps file that points to where the library is installed elsewhere on your system. In either case,…

Forum:Advise for a computational neophyte 0 Hello, biostars! Once I have earned B.Sc. in Biotechnology (in Russia it’s a pretty weird combination of biology, engineering and almost all branches of chemistry), turned to a bigger city to gain a M.Sc. degree. In our research lab we have 2 professors for…
