I am trying to add base pairing restraint between the base from the model and its symmetry related molecule. I went through the tutorial but only found how to add a bond between symmetric molecules instead of the base pairing. Can anybody tell me how to do that please? Many thanks!
The automatic base pairing restraints don't work for symmetry-related molecules at present. Fixing this has been on our to-do list for a while but no one has time to implement it, since it would require significant changes to the way we detect the hydrogen bonds. (It's not actually that difficult to code, but actually testing and validating the new procedure would be quite time-consuming.) You can still set up the base pairing one bond at a time using the custom bond syntax, which is what I'd recommend. The base pairs are simply translated into this restraint type anyway. -Nat
