[gmx-users] How to change the default value for pbc ?

I generated  mdout.mdp

by   grompp -f em.mdp -c ${file}_box.gro -p ${file}.top -o ${file}.input.tpr

The pbc in mdout.mdp is like:

; Periodic boundary conditions: xyz (default), no (vacuum)
; or full (infinite systems only)
pbc                      = xyz

It seems that grompp doesnot give an option to change the pbc value.

I didnot find an easy way to change the pbc value . The only way I found is
to  edit the mdout.mdp directly.
