[gmx-users] Remove PDB and center the protein.

I have simulated protein in a dodecahedron box. I know trjconv can be used
to center the protein and remove PBC but I am confused.
I have tried few cases as follows.
trjconv -f *.xtc -s *.tpr -center -o centered.xtc
trjconv -f centered.xtc -s *.tpr -pbc mol -ur compact -o centered_noPBC.xtc
trjconv -f *.xtc -s *.tpr -pbc mol -ur compact -o noPBC.xtc
trjconv -f noPBC.xtc -s *.tpr -center -o centered_noPBC.xtc
trjconv -f *.xtc -s *.tpr -pbc mol -ur compact -center -o
In all cases, I use protein for centering and system for output. Only third
case keeps protein in center without jumping. What is the best way to
correct trajectory for both visualization and analysis?
