Hello,

with Avogadro I built and optimized simple tri-peptide which I read as pdb into ChimeraX, see the attachments.

When I wanted to display coulombic potential, I got the following error message below.

Looks like Avogadro's  pdb protocol does not fit for ChimeraX...although all atoms and bonds in the tripeptide example are correct. 

Any help, please ?  

The following heavy (non-hydrogen) atoms are missing, which may result in inaccurate electrostatics:
/A GLU 2 CG
/A GLU 2 OE2
/A GLU 2 CA
/A GLU 2 CD
/A GLU 2 CB
/A GLU 2 OE1

Using Amber 20 recommended default charges and atom types for standard residues
Hydrogen /A LEU 3 HO bonded to atom that should not have hydrogens (/A LEU 3 OXT)
