Hello All. I am simulating t4 lysozyme with NAG. I have added a short peptide label to lysozyme which binds calcium ions.
During the simulation there is some drift. I am attempting to re-center the protein+label+NAG+Ca ion. I am using trjconv and have setup an index file that contains only these atom groups (protein+label+NAG+Ca ion). First, I tried just centering using: trjconv -f d61_15_25ns.gro -s md_initial.tpr -n analysis.ndx -center tric -o test.pdb This center's, however NAG and the calcium ion are not in the expected positions. Using: trjconv -f d61_15_25ns.gro -s md_initial.tpr -n analysis.ndx -center tric -o test.pdb -pbc whole The ions and NAG are where they are expected, however, the protein has been split. Using inbox results in something similar. Does anyone know how to do this?
