Dear Amberists;

I am running tleap using AMBER 12 with the following script on a receptor
which is attached herewith. During running the Leap I am encountering this
problem

"
FATAL: Atom .R<NLEU -1>.A<H 22> does not have a type.
Failed to generate parameters
Parameter file was not saved.
Writing pdb file: rec_solvated.pdb
 Converting N-terminal residue name to PDB format: NLEU -> LEU
 Converting C-terminal residue name to PDB format: CLEU -> LEU
Quit
"

I would highly appreciate any response in this regard.
Thank you for all your time.
