This has nothing to do with QM/MM by itself, and should work on
Amber10 as well as Amber9. What version of AmberTools do you have? I'd
recommend that you try downloading the most recent version of
AmberTools (, then apply all the
bugfixes (, then recompile / test /
try again.

Also, unless there's a special reason for you to be doing this
tutorial, I'd recommend that you look at the Amber10 tutorials, in
