2. Note that centering complexes (protein-ligand, protein-protein) may be difficult for longer simulations involving many jumps across periodic boundaries. In those instances (particularly in protein-protein complexes), it may be necessary to create a custom index group to use for centering, corresponding to the active site of one protein or the interfacial residues of one monomer in a complex. GROMACS is free, open-source software, and has consistently been one of the fastest (if not the fastest) molecular dynamics codes available. There are currently seven tutorials available: Lysozyme in Water: The intent of this tutorial is to give new users a basic introduction into the tools used to prepare, run, and perform simple analysis on a The molecule to be inserted should be centered at 0,0,0. GROMACS does not do this for you, since for different situations a different way of centering might be optimal.

Dec 1, 2016 Gromacs has some neat command-line programs to interact with MD trajectories. PIPE) p.communicate(b'1\n0\n') # Center on protein, output Example: Protein-detergent complex The tutorial assumes that you are familiar with the basics of GROMACS.

In the above command, x y z represents the center of mass such that the protein is properly placed. Placement should be based on experimental knowledge of membrane positioning, or intuition based on the chemical composition of your particular protein. 2.

And since i need a structure where the protein remains in the middle of the POPC membrane in order to perform the ‘backward’ step to obtain an AA representation of my system and perform a new MD simulation i’m kind of stuck.
