Gmx hbond contact

WebHydrogen bonds (H-bonds) and contacts in a protein or between protein and ligand are calculated to understand the interactions essential for its function. GROMACS has the hbond utility to calculate the H-bonds and contacts purely from geometric considerations. WebBy the way, the version of gromacs is 2024.3. 1. I used the following command: gmx hbond -s topol.tpr -f md.xtc -n index_contact.ndx -contact -r 0.3 -num contact.xvg -g contact.log -ac contact_ac.xvg in the gromacs manual it is not …

Webgmx hbond computes and analyzes hydrogen bonds. Hydrogen bonds are determined based on cutoffs for the angle Hydrogen - Donor - Acceptor (zero is extended) and the distance Donor - Acceptor (or Hydrogen - Acceptor using -noda ).
