First, I really don't recommend using cpptraj to do topology
conversions. Cpptraj is really only intended for trajectory/data
analysis; it has *not* been vetted at all for converting parameters
between different formats.
Second, by default cpptraj will look for gromacs topology data (that
is not in the same directory) in the directory defined by the GMXDATA
environment variable; specifically, it expects things to be in the
"$GMXDATA/top" directory. I just realized this is not documented
(oops).
Hope this helps,
