Detailed Description

A restraint is a term in an IMP ScoringFunction.

To implement a new restraint, just implement the two methods:

Note
When logging is VERBOSE, restraints should print enough information in evaluate to reproduce the entire flow of data in evaluate. When logging is TERSE the restraint should print out only a constant number of lines per evaluate call.
Physical restraints should use the units of kcal/mol for restraint values and kcal/mol/A for derivatives.

When implementing an expensive restraint it makes sense to support early abort of evaluation if the user is only interested in good scores or scores below a threshold. To do this, look at the fields of the ScoreAccumulator object such as

See IMP::example::ExampleRestraint for an example.

Evaluation convenience methods

These are convenience methods to get the score of just this restraint; each just calls the equivalent method in the ScoringFunction class.

double evaluate_if_good (bool calc_derivatives) const
 
double evaluate_if_below (bool calc_derivatives, double max) const
 

Evaluation implementation

These methods are called in order to perform the actual restraint scoring. The restraints should assume that all appropriate ScoreState objects have been updated and so that the input particles and containers are up to date. The returned score should be the unweighted score.

Note
These functions probably should be called do_evaluate, but were grandfathered in.
Although the returned score is unweighted, the DerivativeAccumulator passed in should be properly weighted.
virtual double unprotected_evaluate (DerivativeAccumulator *da) const
 Return the unweighted score for the restraint. More...
 
virtual double unprotected_evaluate_moved (DerivativeAccumulator *da, const ParticleIndexes &moved_pis, const ParticleIndexes &reset_pis) const
 Return the unweighted score, taking moving particles into account. More...
 
virtual double unprotected_evaluate_if_good (DerivativeAccumulator *da, double max) const
 
virtual double unprotected_evaluate_if_below (DerivativeAccumulator *da, double max) const
 The function calling this will treat any score >= max as bad. More...
 
virtual double unprotected_evaluate_moved_if_below (DerivativeAccumulator *da, const ParticleIndexes &moved_pis, const ParticleIndexes &reset_pis, double max) const
 
virtual double unprotected_evaluate_moved_if_good (DerivativeAccumulator *da, const ParticleIndexes &moved_pis, const ParticleIndexes &reset_pis, double max) const
 

Weights

Each restraint's contribution to the model score is weighted. The total weight for the restraint is the some over all the paths containing it. That is, if a restraint is in a RestraintSet with weight .5 and another with weight 2, and the restraint itself has weight 3, then the total weight of the restraint is \(.5 \cdot 3 + 2 \cdot 3 = 7.5 \).

void set_weight (Float weight)
 
Float get_weight () const
 

Filtering

We are typically only interested in "good" conformations of the model. These are described by specifying maximum scores per restraint (or RestraintSet). Samplers, optimizers etc are free to ignore configurations they encounter which go outside these bounds.

Note
The maximum score is for the unweighted restraint. That is, the restraint evaluation is bad if the value is greater than the maximum score divided by the weight.

Constructor & Destructor Documentation

IMP::Restraint::Restraint ( Model m,
std::string  name 
)

Create a restraint and register it with the model.

IMP::Restraint::Restraint ( )

Default constructor.

Default-constructed restraints cannot be evaluated.

Member Function Documentation

Restraint* IMP::Restraint::create_current_decomposition ( ) const

Decompose this restraint into constituent terms for the current conf.

Returns
a decomposition that is value for the current conformation, but will not necessarily be valid if any of the particles are changed. This is the same as create_decomposition() for non-conditional restraints.

The restraints returned have had set_model() called and so can be evaluated.

Restraint* IMP::Restraint::create_decomposition ( ) const

Decompose this restraint into constituent terms.

Given the set of input particles, decompose the restraint into parts that are as simple as possible. For many restraints, the simplest part is simply the restraint itself.

If a restraint can be decomposed, it should return a RestraintSet so that the maximum score and weight can be passed properly.

The restraints returned have had set_model() called and so can be evaluated.

virtual ScoringFunction* IMP::Restraint::create_scoring_function ( double  weight = 1.0,
double  max = NO_MAX 
) const
virtual

Create a scoring function with only this restraint.

Note
This method cannot be implemented in Python due to memory management issues (and the question of why you would ever want to).
virtual Restraints IMP::Restraint::do_create_current_decomposition ( ) const
protectedvirtual

A Restraint should override this if it wants to decompose itself for display and other purposes. The returned restraints will be made into a RestraintSet if needed, with suitable weight and maximum score.

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

Reimplemented in IMP::core::ExcludedVolumeRestraint, IMP::core::MSConnectivityRestraint, and IMP::core::ConnectivityRestraint.

virtual Restraints IMP::Restraint::do_create_decomposition ( ) const

A Restraint should override this if it wants to decompose itself for domino and other purposes. The returned restraints will be made into a RestraintSet if needed, with suitable weight and maximum score.

Reimplemented in IMP::core::ExcludedVolumeRestraint.

dynamic key:value information about this restraint, or null.
a set of key:value pairs that contain dynamic information about this restraint (i.e. information that changes during a sampling run, such as scores or cross correlations). If no such information is available, a null pointer is returned. This information is used when writing restraints to files, e.g. by the IMP.rmf module.

Reimplemented in IMP::bayesianem::GaussianEMRestraint, IMP::isd::GaussianEMRestraint, IMP::em2d::PCAFitRestraint, and IMP::isd::UniformPrior.

bool IMP::Restraint::get_is_aggregate ( ) const

Return whether this restraint wraps a number of other restraints.

Definition at line 291 of file Restraint.h.

double IMP::Restraint::get_last_last_score ( ) const

Get the unweighted score from the last-but-one time it was evaluated.

See Also
get_last_score

Definition at line 288 of file Restraint.h.

virtual double IMP::Restraint::get_last_score ( ) const
virtual

Return the (unweighted) score for this restraint last time it was evaluated.

Note
If some sort of special evaluation (eg Model::evaluate_if_good()) was the last call, the score, if larger than the max, is not accurate.

Reimplemented in IMP::RestraintSet.

Definition at line 283 of file Restraint.h.

double IMP::Restraint::get_score ( ) const

Compute and return the current score for the restraint.

virtual RestraintInfo* IMP::Restraint::get_static_info ( ) const
virtual
Returns
static key:value information about this restraint, or null.
a set of key:value pairs that contain static information about this restraint (i.e. information that doesn't change during a sampling run, such as the type of restraint or filename from which information is read). Usually this includes a "type" key with the fully qualified classname (e.g. IMP.mymodule.MyRestraint). If no such information is available, a null pointer is returned. This information is used when writing restraints to files, e.g. by the IMP.rmf module.

virtual double IMP::Restraint::unprotected_evaluate_moved ( DerivativeAccumulator da,

) const
virtual

Return the unweighted score, taking moving particles into account.

By default this just calls regular unprotected_evaluate(), but may be overridden by restraints to be more efficient, e.g. by skipping terms that involve unchanged particles.

Parameters
daObject to accumulate derivatives, or nullptr.
moved_pisParticles that have moved since the last scoring function evaluation.
reset_pisParticles that have moved, but back to the positions they had at the last-but-one evaluation (e.g. due to a rejected Monte Carlo move).
Returns
Current score.

Reimplemented in IMP::isd::LogWrapper.
