[gmx-users] Protein is not at the centre of octahedron box

[sukesh chandra gain]

Dear All,
I am doing a simulation for ligand-enzyme complex in a octahedron box. I 
have mentioned -c with editconf, but after energy minimization the 
protein is placed at the top of the box. Could you please suggest me how 
could I keep the protein at the centre of the octahedron box?
Here are the details:

Thank You,
