[Chimera-users] LINK record not honoured in Chimera?

Hello, I would like to visualize a thioester bond between a CYS residue of my protein and a carbonyl carbon of ligand (DCR) in my model. I have a LINK record for the DCR-CYS thioester bond created from Jligand and inserted in the PDB right before the CRYST1 line. However, when I open this PDB in Chimera, the thioester linkage is not drawn. The distance between the C1 of DCR and SG of CYS is 1.79 angstrom. Does Chimera need something else other than the LINK record in the PDB to display the bond? Thank you, Kate
