[Chimera-users] Pseudobonds in mmCIF

The simpler command is
… but I am confused because in my tests of opening 1www.cif (which has examples of missing segments pseudobonds) they are listed in the Pseudobond Panel as “missing segments” and these commands also work:
setattr p display false
setattr g display false
I’m testing with Chimera version 1.12.
Your description makes me think the offending connections may actually be bonds, not pseudobonds. To say any more, we’d have to see the file… maybe something in there is wrong.
If they are bonds, you can delete them with the ~bond command or in the Build Structure tool (in menu under Tools… Structure Editing) Adjust Bonds section.
My only other idea is that they result from autochaining, which you can turn off with command:
setattr m autochain 0
(that’s a zero)
I hope this helps,
