Deposition on the surface of cylinder

Dear Lammps users,

I am trying to deposit silver on the surface of Cu NWs.
I mimic the deposition on the thin film, however, there is an error.

ERROR: Fix deposit region does not support a bounding box (…/fix_deposit.cpp:73)

Can you help me to fix this?

Best,
Choi

… And there is an error message and the LAMMPS manual. If you read in the latter about the former, you will get already a good explanation of what you are trying to do cannot work.
