Detailed Description

template<class UF>
class IMP::core::GenericBoundingBox3DSingletonScore< UF >

A generic C++ template for scoring particles based on how far outside a box they are using unary function UF. The bounding box score is evaluated by applying a function f of class UF to a particle based on the distance of its center from the bounding box walls. The radius of the particle is ignored. If the particle is within the bounding box, the score is always 0. Logically, it is expected that f(0) = 0 and f(x) > 0 if x>0.

In Python, use the templated BoundingBox3DSingletonScore class as in the following example. In the example, 10 particles of radius 1.0 are generated in a 10 A x 10 A x 10 A bounding box. The particles are restrained in the bounding box by applying an upper-bounded harmonic potential. It is upper bounded because it is active only outside the bounding box.

 k_bb = 10.0 # bounding box force coefficient in kcal/mol/A^2
 bb_side = 10.0 # in A
 radius = 1.0 # in A
 number
 m = IMP.Model()
 bb = IMP.algebra.BoundingBox3D(IMP.algebra.Vector3D(0, 0, 0),
                            IMP.algebra.Vector3D(bb_side, bb_side, bb_side))
 particles = []
 for i in range(0,10):
   p = IMP.Particle(m) 
   s = IMP.algebra.Sphere3D(
             IMP.algebra.get_random_vector_in(bb), radius)
   d = IMP.core.XYZR.setup_particle(p, s)
   d.set_coordinates_are_optimized(True)
   particles.append(p)
 hpb = IMP.core.HarmonicUpperBound(0, k)
 bbss = IMP.core.BoundingBox3DSingletonScore(hpb, bb) 
 bbr = IMP.container.SingletonsRestraint(bbss, particles)

template<class UF >

IMP::core::GenericBoundingBox3DSingletonScore< UF >::GenericBoundingBox3DSingletonScore	(	UF *	f,
		const algebra::BoundingBoxD< 3 > &	bb
	)

Parameters

f	an unary function applied to particles that are outside the box. f is passed the distance of the particle center from the bounding box walls, ignoring the particle radius. Logically, it is expected to satisfy f(0) = 0 and f(x) > 0 if x>0.
bb	the bounding box to which f is applied

Member Function Documentation

template<class UF >

virtual ModelObjectsTemp IMP::core::GenericBoundingBox3DSingletonScore< UF >::do_get_inputs	(	Model *	m,
		const ParticleIndexes &	pis
	)		const

overridevirtual

Overload this method to specify the inputs.

Implements IMP::ParticleInputs.

Definition at line 87 of file BoundingBox3DSingletonScore.h.

Here is the call graph for this function:

template<class UF >

double IMP::core::GenericBoundingBox3DSingletonScore< UF >::evaluate_if_good_indexes	(	Model *	m,
		const ParticleIndexes &	o,
		DerivativeAccumulator *	da,
		double	max,
		unsigned int	lower_bound,
		unsigned int	upper_bound
	)		const

overridevirtual

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.

Returns: the score if score<= max or some arbitrary value > max otherwise.

Note: An implementation for this is provided by the IMP_SINGLETON_SCORE_METHODS() macro.

Reimplemented from IMP::SingletonScore.

template<class UF >

virtual double IMP::core::GenericBoundingBox3DSingletonScore< UF >::evaluate_index	(	Model *	m,
		ParticleIndex	p,
		DerivativeAccumulator *	da
	)		const

overridevirtual

return 0 if the p is within the bounding box or f(d) if it is outside the bounding box, where f is the unary function provided during construction and d is the distance of the center of p from the bounding box walls. Update derivatives as needed, weighted using da.

Implements IMP::SingletonScore.

	)		const

finaloverridevirtual

Compute the score and the derivative if needed over a set.

Parameters

m	the model of o
o	objects of type Particle, specified by index
da	a derivative accumulator that weights computed derivatives. If nullptr, derivatives will not be computed.
lower_bound	index of first item in o to evaluate
upper_bound	index one past last item in o to evaluate

	)		const

finaloverridevirtual

Compute the change in score and the derivative if needed over a set.

The score for each o[indexes[x]] is updated in score[indexes[x]] and the total difference between the old and new score values (over the set) is returned.

Note: An implementation for this is provided by the IMP_SINGLETON_SCORE_METHODS() macro.

Reimplemented from IMP::SingletonScore.
