[Chimera-users] Attribute "distance" generated by shortcut "ac sd" not saved between sessions?

Very nice image! Thanks for the script; should it work for most people with a recent version of HOLE, or does it need to be tailored for a specific situation? I might keep it for myself to try later.
Sorry, I think it's a bug where “ac sd" should mark the distance attribute as something to be saved in a session, but it doesn’t.
Sorry about that… in the meanwhile, the somewhat annoying workaround (but only needs to be done once) is to save the attribute to a file, read it back in with defattr, and then save the session. The Render by Attribute dialog has menu item File… Save Attributes and that creates the correct format for reading back in with defattr.
