Hwo to Pull Peptide from the Middle?

Hi everyone,

Successfully performed pulling molecular dynamics (MD) on a peptide docked to a protein. Now seeking guidance on adjusting .mdp file for pulling the peptide from the middle. Any suggestions?

If it’s just pulling from the middle without biasing the orientation, the pull code with two groups with both COMs and a coordinate for the distance will do it. You can do steered MD by setting the pull rate or do adaptive sampling with AWH. There are tutorials for AWH.
