[Chimera-users] Disulfide bond for minimization?

Okay, I have found the problem and committed a fix.  The fix will be in tonight's daily build and will be in the 1.10.1 release (if we make one).  The problem affects all structures with "unusual" bonds involving standard residues (disulfides, glycosylations, etc.).

But when entering the minimization run, chimera complains about the atoms of the cysteinate residues. Before sending you files I was just wondering if this is something that is not implemented in chimera or a problem on how I prepare my structure.
