That should be fine. A bit slow maybe.

Maybe try fitting to a blurred map?


When I drag or remove the restraints it collapses (base pairing, planarity is destroyed.)


(i) Too fast or too extensive drag, try 10 micro-yanks instead of one big yank

(ii) alpha too high

(iii) map to model weight too high


But that will be a thing of the past in 0.9.1.
