Detailed Description

Given an arbitrary collection of particles and rigid bodies, this restraint prevents the particles from interpenetrating. Such restraints are also known as steric clash restraints.

Note
Pairs of particles within a single rigid body are not restrained (and are ignored in the returned score).
See IMP::container::ClosePairContainer for more information about close pair based scoring functions and IMP.
Changing the set of particles in the SingletonContainer is not currently supported after the first evaluate call.

Constructor & Destructor Documentation

IMP::core::ExcludedVolumeRestraint::ExcludedVolumeRestraint ( SingletonContainerAdaptor  sc,
double  k = 1,
double  slack = 10,
std::string  name = "ExcludedVolumeRestraint%1%" 
)

The SingletonContainer contains a set of XYZR particles and RigidMembers.

The slack is how far the particles must move before the list of close pairs is computed. It does not matter for correctness, just running time. You may want to fiddle with it or use the IMP::container::get_slack_estimate() function.

The spring constant used is k.

Member Function Documentation

void IMP::core::ExcludedVolumeRestraint::clear_caches ( )
virtual

Objects can have internal caches. This method resets them returning the object to its just-initialized state.

Reimplemented from IMP::base::Object.

kernel::Restraints IMP::core::ExcludedVolumeRestraint::do_create_current_decomposition ( ) const
virtual

A Restraint should override this if they want to decompose themselves for display and other purposes. The returned restraints will be made in to a RestraintSet, if needed and the weight and maximum score set for the restraint set.

The returned restraints should be only the non-zero terms and should have their last scores set appropriately;

Reimplemented from IMP::kernel::Restraint.

kernel::Restraints IMP::core::ExcludedVolumeRestraint::do_create_decomposition ( ) const
virtual

A Restraint should override this if they want to decompose themselves for domino and other purposes. The returned restraints will be made in to a RestraintSet, if needed and the weight and maximum score set for the restraint set.

Reimplemented from IMP::kernel::Restraint.

IMP::kernel::ModelObjectsTemp IMP::core::ExcludedVolumeRestraint::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.
