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: ## \example core/restrain_in_sphere.py # This fragment shows how to restrain a set of points stored in a # SingletonContainer in a sphere of radius 'radius' centered around # 'center'. import IMP import IMP.core import sys IMP.setup_from_argv(sys.argv, "restrain in sphere") radius = 10 stiffness = 2 center = IMP.algebra.Vector3D(1, 2, 3) m = IMP.Model() p = m.add_particle("particle") IMP.core.XYZR.setup_particle( m, p, IMP.algebra.Sphere3D(IMP.algebra.Vector3D(100, 0, 0), 1)) 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.core.SingletonRestraint(m, ss, p) r.evaluate(False)

Compute the score and the derivative if needed over a set, only if "good". This functions similarly to evaluate_indexes(), but may terminate the computation early if the total score is higher than max.
