[Chimera-users] problems in opening PDB file

[Eric Pettersen]

Hi Laura,
	The “loop bond” message specifically means that your PDB file has a CONECT or LINK record that says that an atom is bonded to itself!  So my advice would be to edit your PDB file and remove all CONECT and LINK records and let Chimera figure out the bonds on its own.
