Detailed Description

Score the improper dihedral based on a UnaryFunction,.

This scores the improper dihedral using information stored in its Dihedral decorator. The score is based on the difference between the stored ideal improper angle and the actual angle and scaled by the stiffness. That is stiffness * (improper_angle-ideal_value). The difference is in radians between -pi and +pi; it is the shortest distance from one angle to the other.

Just as for regular dihedral angles, the improper angle is defined as the angle between the plane in which the first three atoms lie and the plane in which the last three atoms lie.

Note
The multiplicity of the the Dihedral is not used.

Member Function Documentation

virtual kernel::ModelObjectsTemp IMP::atom::ImproperSingletonScore::do_get_inputs ( kernel::Model m,
const kernel::ParticleIndexes pis 
) const
virtual

Overload this method to specify the inputs.

Reimplemented from IMP::kernel::ParticleInputs.

double IMP::atom::ImproperSingletonScore::evaluate_if_good_indexes ( kernel::Model m,
const kernel::ParticleIndexes o,
DerivativeAccumulator da,
double  max,
unsigned int  lower_bound,
unsigned int  upper_bound 
) const
virtual

Compute the score and the derivative if needed as in evaluate_index(). 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.

Implementations for these are provided by the IMP_SINGLETON_SCORE() macro.

Reimplemented from IMP::kernel::SingletonScore.
