[Chimera-users] Question about the dotted bond

There are a few possible reasons, but it depends on the specific PDB
file. Dotted lines are usually "pseudobonds," used to show where
parts of chains are missing (such as a missing loop in a PDB
structure due to poor density), metal complexation bonds, and
You can hide it if you want by Ctrl-clicking to select it and then
opening the Selection Inspector (by clicking the button on the lower
right corner of the Chimera window) - in there, set "displayed" to
"false". Or, you can open the PseudoBond Panel (under Tools...
General Controls), click on the Name of that pseudobond group
(different names are used for different situations), and then on the
right side click close (delete) or hide. Or, you just could change
how it looks by clicking "attributes..." and adjusting parameters in
the resulting dialog.
I hope this helps,
