But error occured..
ERROR 1 [file ffgmxnb.itp, line 270]:
Trying to add Buck.ham (SR) while the default nonbond type is LJ (SR)
ERROR 2 [file ffgmxnb.itp, line 271]:

I think I have indicated that the function type is 2 (means Buckingham).
Anything else need to do with this ?
... specify that the default nonbonded type is not LJ? Have a look in
Chapter 5 of the manual.
Also, I want to fix some atoms in the boundary and specify displacement
to some atoms, anayone knows how to do this?
You can freeze groups of atoms, or use position restraints, or pull
groups of atoms, but you should look first in the manual for the
information that is there.
