Copper is not currently available due to the need for d-orbitals which are
not yet supported (but should be in a future release). Hence right now you
cannot include copper in your QM region unless you use something like Pupil
and hook it to an external program but this of course comes with a massive
performance hit and the inability to run with full periodic boundaries and
long range electrostatics.
All the best
Ross
