I'll post my pdb here
http://boinc.drugdiscoveryathome.com/fzd8min_renum_SS.pdb
Seems that this file only gives me that message when I add hydrogens
before opening in tleap. I tried it again without adding hydrogen but
instead I ran this command to replace residues

total atoms in file: 3844
Leap added 494 missing atoms according to residue templates:
494 H / lone pairs
The file contained 914 atoms not in residue templates

Writing pdb file: receptor.pdb
Converting N-terminal residue name to PDB format: NGLU -> GLU
Converting C-terminal residue name to PDB format: CARG -> ARG
Converting N-terminal residue name to PDB format: NGLU -> GLU
Converting C-terminal residue name to PDB format: CARG -> ARG
but the reason I wanted to add hydrogens can be revealed in my next
step when I try to prep it for Gromacs, which is off topic for this
list
pdb2gmx -ff amber99sb -f receptor.pdb -ignh
I get this error message
WARNING: atom H is missing in residue GLU 1 in the pdb file
You might need to add atom H to the hydrogen database of residue GLU
in the file ff???.hdb (see the manual)
So I also tried adding hydrogens after tleap but got the same error
message when I preped it for gromacs
pdb2gmx -ff amber99sb -f Protein3.pdb -ignh
These are the GLU 1 atoms before using babel to add H
