Dear Amber uses,
I have been trying to generate prmtop and inpcrd files for pdb id 1eve
protonated using H++ server and standardized through pdb4amber. When using
tleap it creates two new H atom under two residues which seems to cause the
error. I didn't use reduce in amber which then would changes protonation
states in my pdb file. On using original pdb file from the database
standardized using pdb4amber also results in the same error.
Loading PDB file: ./ache-amber.pdb
Created a new atom named: HE2 within residue: .R<GLU 277>
Created a new atom named: HD2 within residue: .R<ASP 391>
total atoms in file: 8386
The file contained 2 atoms not in residue templates
Checking 'ache'....

What could be the reason and possible solution?
