Hi Eric
Problems with atom names in adding charge to a receptor using Chimera v1.13.1
(ToolsàSurface Binding/AnalysisàAdd charge)
I first added my H to prepare my receptor. And I am using the protein PDB ID 2BXF.
Net Charge is +0 for the residue HIS using charge method AM1_BCC
Chimera warning received
Correct charges are unknown for 9 non-standard atom names in otherwise standard residues.
Charges of 0.0 were assigned to the unknown atoms.
1 model(s) had non-intergral total charge.
Reply log is as follows,
Charge model: AMBER ff14SB
Assigning partial charges to residue HIS (net charge +0) with am1-bcc method
