Deposition of molecules with fix-deposit command?

Hi

I am a graduate student at University of Florida in Materials Science and Engg department. I want to deposit molecules on a substrate, but the fix deposit command has the provision to deposit only single atom. Could you please guide me how to accomplish the work?

Fix deposit only currently works for atoms. If you want it to work
for molecules you'd have to extend it, by writing new code. If you're
successful
we'd be happy to add it to LAMMPS.
