Dear Alan, This depends very much on whether the structures are similar in the helical conformations or not, and on what question you are trying to address. If these are nearly identical structures, it really does not matter much what atoms you use for superposition, as long as they lie along the

Dear all - is there a convention for superposing nucleic acids duplexes of unrelated sequence? i.e. which atoms should be superposed : C4' of the sugar, P of the backbone, O3'/O5' of the backbone, or some combination thereof? Alan -- Alan Cheung Gene Center Ludwig-Maximilians-University Feo
