Constructor & Destructor Documentation

IMP::npctransport::Scoring::Scoring ( SimulationData owner_sd,
const ::npctransport_proto::Assignment &  data 
)
Parameters
[in]owner_sdnpc simulation data object that owns this scoring object
[out]dataprotobuf data with parameters for this assignment, used to parameterize the scoring function

Member Function Documentation

void IMP::npctransport::Scoring::add_chain_restraints ( FGChain chain)

add FG chain to this scoring object, using the chain->get_chain_restraints() method to retrieve the restraints upon a call to get_scoring_function() or create_scoring_function(), etc.

Parameters
chainan FG chain associated with internal scoring
Returns
pointer to the newly created restraint
Note
if the chain->get_backbone_k() is non-positive, it is reset to this->get_default_backbone_k()
this method assumes that all such chains will be disjoint and so it is later possible to use container::ExclusiveConsecutivePairFilter to filter out all pairs of particles connected by such chain restraints.
void IMP::npctransport::Scoring::add_interaction ( const ::npctransport_proto::Assignment_InteractionAssignment &  idata)

add a SitesPairScore restraint that applies to particles of types t0 and t1 (specified in idata) to the PredicatePairsRestraint object that is returned by get_predr(). The restraint is symmetric, and applies to both (t0,t1) and (t1,t0).

A SitesPairScore restraint means site-specific attractive forces between surface binding sites on each particle + non-specific attraction and soft repulsion between the entire particles.

Parameters
idatathe protobuf data about the interaction (particle types, interaction coefficients, etc.)
See Also
SitesPairScore
void IMP::npctransport::Scoring::add_restrained_anchor_bead ( IMP::Particle p)

add anchor bead to scoring function, using current position of p as equilibrium position relative to pore

Parameters
panchored particle
Note
currently only cylindrical pore case is supported
void IMP::npctransport::Scoring::add_z_bias_restraint ( SingletonContainerAdaptor  ps,
double  k 
)

adds a biasing potential for particles ps towards z, to the restraints returned by get_z_bias_restraints(), and for the scoring function generated by get_scoring_function()

Parameters
pscontainer for the particles to be biased
kforce constant
See Also
get_z_bias_restraints()
get_scoring_function()
void IMP::npctransport::Scoring::add_z_bias_restraint ( Particle p,
double  k 
)

adds a biasing potential for particle p towards z, to the restraints returned by get_z_bias_restraints(), and for the scoring function generated by get_scoring_function()

Parameters
pthe particle to be biased
kforce constant
boost::tuple< Restraint*, Object*> IMP::npctransport::Scoring::create_backbone_restraint ( double  rest_length_factor,
double  backbone_k,
ParticlesTemp  beads,
std::string  name 
) const

Create a backbone bond restraint over beads according to class flags.

create a backbone bond restraint with specified rest_length_factor (relative to sum of spheres radii) and backbone k over beads. The restraint score type is according to the class flags - either a linear or harmonic potential, with k in units of kcal/mol/A or kcal/mol/A^2, respectively, with the harmonic potential corresponding to a relaxing spring.

returns both the restraint and the linear well pair score or harmonic singleton score that is used in it (which one depends on the IMP version, assigns nullptr to the other), as a pointer to a generic object (= common ancestor class)

Restraint* IMP::npctransport::Scoring::create_bounding_volume_restraint ( SingletonContainerAdaptor  beads) const

Creates bounding volume (box or sphere) restraint based on the box_size_ class variable and get_has_bounding_sphere() and get_has_bounding_box() variables (typically based on box_is_on_), , and apply it to all beads returned by get_sd()->get_beads()

Parameters
beadsbeads on which to apply the constraint
Note
this restraint is (supposed to) guarantee to be always updated with the list inside the container
Returns
a newly created box restraint
IMP::PairContainer* IMP::npctransport::Scoring::create_close_beads_container ( SingletonContainerAdaptor  non_optimiziable_beads,
SingletonContainerAdaptor  optimizable_beads 
) const

creates a new pair container that returns all pairs of particles (a,b) such that: 1) a is any particle from 'non_optimizable_beads' or 'optimizable beads', and b is any particle in 'optimizable_beads' 2) a and b are close (sphere surfaces within range get_range()) 3) a and b do not appear consecutively within the model (e.g., fg repeats) 4) a is not b 5) b and a do not appear in the list (effectively, a list of unordered pairs)

Parameters
non_optimizable_beadsa container for particles that are assumed to be non-optimizable and therefore are not paired among themselves
optimizable_beadsA container for particles that are assumed to be optimizable, and may be paired among themselves or with non_optimizable_beads
Note
it is assumed the two sets of beads are disjoint
IMP::PairContainer* IMP::npctransport::Scoring::create_close_beads_container ( ParticleIndexes  non_optimizable_beads,
SingletonContainerAdaptor  optimizable_beads 
) const

same as other create_close_beads_container variant but based on a list of particle indexes and allowing an empty vector of non-optimizable beads as input. The optimizable beads are still treated dynamically (e.g. if they're associated with a dynamic container)

Definition at line 364 of file Scoring.h.

container::PredicatePairsRestraint* IMP::npctransport::Scoring::create_predicates_pair_restraint ( PairContainer bead_pairs,
bool  is_attr_interactions_on = true 
) const

Creates a new container for restraints over pairs of beads. Different scores are used for beads of different (ordered) particle types based on interaction_pair_scores, or just a default linear repulsive with k=get_excluded_volume_k() force on all other pairs in bead_pairs.

Parameters
bead_pairsa container for the pairs of beads to be restrained
is_attr_interactions_onwhether to include attractive interactions that were added by add_interaction()
Restraint* IMP::npctransport::Scoring::create_slab_restraint ( SingletonContainerAdaptor  beads) const

Creates slab bounding volume restraint, based on the slab_thickness_ and tunnel_radius_ class variables, and apply it to all beads returned by get_sd()->get_beads()

Parameters
beadsbeads on which to apply the constraint
Note
this restraint is (supposed to) guarantee to be always updated with the list inside the container
Returns
a newly created slab restraint
IMP::Restraint* IMP::npctransport::Scoring::create_z_bias_restraint ( SingletonContainerAdaptor  ps,
double  k 
) const

create a z bias restraint pulling along z-axis for the particles in ps. If a slab is present, the force acts only within tunnel radius distance from its central axis.

Parameters
psthe particles container
kforce constant for biasing ps
Restraints IMP::npctransport::Scoring::get_all_chain_restraints ( ) const
Returns
all restraints of fg nup chains that were added by add_chain_restraints() so far
Restraint* IMP::npctransport::Scoring::get_bounding_volume_restraint ( bool  update = false)

returns the box/sphere restraint on >get_sd()->get_beads() which will be used in the next call to get_scoring_function(false) (so manipulating it might affect the scoring function). If update is false, then it is guaranteed that these are the same restraints used by the last call to get_scoring_function.

Parameters
updateif true, forces recreation of the cached container, o/w cached version that was used in last call to get_scoring_function(), if applicable
Note
if udpate=false, might fail to include e.g., new particles that were added after the last call
See Also
get_has_bounding_box(), get_has_bounding_sphere(), get_has_bounding_volume()
Restraints IMP::npctransport::Scoring::get_chain_restraints_on ( SingletonContainerAdaptor  beads) const

returns restraints on all fg nup chains that were added by add_chain_restraints() so far and contain any bead in 'beads'. The restraints are updated directly from the original chain objects chain->get_chain_restraints() object.

Parameters
beadsa least of chain fine beads over which restraints are collected
Returns
a list of all chain restraints that have been added so far and contain beads in 'beads'
IMP::PairContainer* IMP::npctransport::Scoring::get_close_beads_container ( bool  update = false)

a pair container that was used to define interaction particles that will be used in the next call to get_scoring_function(false) (so manipulating it might affect the scoring function)

Parameters
updateif true, forces recreation of the cached container, o/w cached version that was used in last call to get_scoring_function() or to this function will be used
Returns
a container with all pairs of particles (a,b) such that: 1) a is an optimizable bead particle and b is any bead particle (static or not). 2) a and b are close (sphere surfaces within range get_range()+some slack) 3) a and b do not appear consecutively within the model (e.g., bonded fg motifs) 4) a and b are not the same particles 5) b and a do not appear on the list (= unordered list)
Note
if udpate=false, might fail to include e.g., new particles or new interactions that were added after the last call
TODO: right now will not return any consecutive particles - that's erroneous (e.g., last particle of one chain and first particle of next chain) though may be negligible in practice
supposed to be robust to dynamic changes to the beads list, though need to double check (TODO)
