Hay,
I am sure that this is a dumb problem BUT I am unable to “turn on” the disulfide bonds in my structures. They are a crucial part of the structures that I am publishing and I really would like to use Chimera to render the images for our publication but I am not a code guy and none of the combos I have tried worked. If anyone is out there with the answer please let me know!
Thanks!
You can also add the linkages directly in Chimera. If you select a pair of sulfurs that should have the linkage, then the command "bond sel" (Favorites->Command Line) will add the linkage. Sessions and PDB files that you save thereafter will have the linkage information (i.e. a saved PDB file will have the appropriate CONECT record).
If you have a lot of disulfide bonds or a lot of structures, I could send you a short Python script to add the linkages automatically.
