WebNow we have verified that all the necessary atoms are present and the PDB file contains only protein atoms, and is ready to be input into GROMACS (see GROMACS documentation ). The first GROMACS tool, we use, is pdb2gmx. The purpose of pdb2gmx is to generate three files: The topology for the molecule. A position restraint file. WebDec 10, 2024 · By. Dr. Muniba Faiza. Gromacs [1] is one of the most widely used software for molecular dynamics (MD) simulation of macromolecules. One of the previous articles, explains the installation of Gromacs on Ubuntu.
