Constructor & Destructor Documentation

IMP::em::FitRestraint::FitRestraint	(	kernel::ParticlesTemp	ps,
		DensityMap *	em_map,
		FloatPair	norm_factors = `FloatPair(0., 0.)`,
		FloatKey	weight_key = `atom::Mass::get_mass_key()`,
		float	scale = `1`,
		bool	use_rigid_bodies = `true`,
		KernelType	kt = `GAUSSIAN`
	)

Parameters

[in]	ps	The particles participating in the fitting score
[in]	em_map	The density map used in the fitting score
[in]	norm_factors	if set, they are used as normalization factors for the cross correlation calculations. This is relevant when the cross-correlation score of the entire system is decomposed.
[in]	weight_key	the name of the weight attribute of the particles
[in]	scale	multiply the fitting restraint score and derivatives by this value
[in]	use_rigid_bodies	if some of the particles are part of a rigid body, use the rigid body for faster calculations
[in]	kt	KernelType to use for simulating density from particles

Note: Rigid-bodies are interpolated and not resampled if use_rigid_bodies option is selected. This significantly reduces the running time but is less accurate. If the user prefers to get more accurate results, provide its members as input particles and not the rigid body.

Member Function Documentation

virtual IMP::kernel::ModelObjectsTemp IMP::em::FitRestraint::do_get_inputs ( ) const

virtual

Get any Particle, Container or other ModelObjects read by this during evaluation. If you read everything in a container, you can just return that container.

Implements IMP::kernel::ModelObject.

SampledDensityMap* IMP::em::FitRestraint::get_model_dens_map ( ) const

Returns: the predicted density map of the model
