Hi Justin,
 I have corrected the ffcharmm.itp file. But I am still getting the error:
Back Off! I just backed up mdout.mdp to ./#mdout.mdp.1#
checking input for internal consistency...
processing topology...
Generated 0 of the 595 non-bonded parameter combinations

-------------------------------------------------------
Program grompp_d, VERSION 4.0.5
Source code file: toppush.c, line: 1273

Fatal error:
[ file topol.top, line 3879 ]:
Atom index (1) in settles out of bounds (1-0).
This probably means that you have inserted topology section "settles"
in a part belonging to a different molecule than you intended to.
In that case move the "settles" section to the right molecule.
-------------------------------------------------------

Thanks
Chanchal
