[gmx-users] center an atomic group

[Dr. Vitaly V. G. Chaban]

Dear All -

I have a macromolecule surrounded by multiple layers of water in my
box. For visualization purposes, I would like to center the
macromolecule in the box (PDB file), so that its geometrical center
coincides with the geometrical center of the cubic box (as
visualization utilities undertand this center).

Would anyone please suggest a handy route within the gromacs utilities
to achieve this? I tried to use

editconf -center $macromol_center_coords -f conf.gro -o conf.pdb

I am not sure what it exactle does, but the macromolecule was not at
the center of the box.

Thank you.
