Apply a function to the distance to a fixed point.
A particle is scored based on the distance between it and a constant point as passed to a UnaryFunction. This is useful for anchoring constraining particles within a sphere.
To restrain a set of particles store in SingletonContainer pc in a sphere do the following: import IMP.example radius=10 stiffness=2 center= IMP.algebra.Vector3D(1,2,3) (m,c)=IMP.example.create_model_and_particles() ub= IMP.core.HarmonicUpperBound(radius, stiffness) # Restrain based on the distance to a single point (hence a ball ss= IMP.core.DistanceToSingletonScore(ub, center) r= IMP.container.SingletonsRestraint(ss, c) m.add_restraint(r) m.evaluate(False)
