Standard module methods
All `IMP` modules have a set of standard methods to help get information about the module and about files associated with the module.
std::string	get_module_version ()

std::string	get_module_name ()

Dope scoring
`IMP` provides the DOPE scoring function for scoring proteins. Note These are quite large objects as they store the whole DOPE lookup table. It is much better to share them between restraints than to create separate instances.
typedef score_functor::DopeType	DopeType

void	add_dope_score_data (atom::Hierarchy h)

Estimator Functions
These functions allow you to estimate physical quantities relating to biomolecules.
enum	ProteinDensityReference { ALBER, HARPAZ, ANDERSSON, TSAI, QUILLIN, SQUIRE }

double	get_protein_density_from_reference (ProteinDensityReference densityReference)

double	get_volume_from_mass (double m, ProteinDensityReference ref=ALBER)
	Estimate the volume of a protein from its mass. More...

double	get_mass_from_volume (double v, ProteinDensityReference ref=ALBER)
	Estimate the mass of a protein from its volume. More...

double	get_mass_from_number_of_residues (unsigned int num_aa)
	Estimate the mass of a protein from the number of amino acids. More...

double	get_volume_from_residue_type (ResidueType rt)
	Return an estimate for the volume of a given residue. More...

Simplification along backbone
These two methods create a simplified version of a molecule by merging residues sequentially. In one case every n residues are merged, in the other, the intervals are passed manually. The resulting molecule is not optimized by default and has no restraints automatically created. At the moment, the calls only support unmodified hierarchies loaded by read_pdb() which have only protein or DNA members. They return Hierarchy() if the input chain is empty. If keep_detailed is true, then the original high resolution structure particles are added as children of the simplified structure.
Hierarchy	create_simplified_along_backbone (Hierarchy input, int num_res, bool keep_detailed=false)

Hierarchy	create_simplified_along_backbone (Chain input, const IntRanges &residue_segments, bool keep_detailed=false)

Finding information
Get the attribute of the given particle or throw a ValueException if it is not applicable. The particle with the given information must be above the passed node.
std::string	get_molecule_name (Hierarchy h)

Ints	get_residue_indexes (Hierarchy h)

ResidueType	get_residue_type (Hierarchy h)

int	get_chain_id (Hierarchy h)

AtomType	get_atom_type (Hierarchy h)

std::string	get_domain_name (Hierarchy h)

int	get_copy_index (Hierarchy h)

Mol2 IO
`IMP` can also read and write Mol2 files. As with read_pdb(), selector objects are used to determine which atoms are read. The read function produces a hierarchy containing the molecule. The write hierarchy writes all the Residue types in the hierarchy to the file.
Hierarchy	read_mol2 (base::TextInput mol2_file, kernel::Model model, Mol2Selector mol2sel=nullptr)
	Create a hierarchy from a Mol2 file.

void	write_mol2 (Hierarchy rhd, base::TextOutput file_name)
	Write a lignand hierarchy as a mol2 file. More...

PDB Reading
The read PDB methods produce a hierarchy that looks as follows: One Atom per ATOM or HETATM record in the PDB. All Atom particles have a parent which is a Residue. All Residue particles have a parent which is a Chain. Waters are currently dropped if they are ATOM records. This can be fixed. The read_pdb() functions should successfully parse all valid pdb files. It can produce warnings on files which are not valid. It will attempt to read such files, but all bets are off. When reading PDBs, PDBSelector objects can be used to choose to only process certain record types. See the class documentation for more information. When no PDB selector is supplied for reading, the NonWaterPDBSelector is used. Set the IMP::LogLevel to VERBOSE to see details of parse errors.

PDB Writing
The methods to write a PDBs expects a Hierarchy that looks as follows: all leaves are Atom particles all Atom particles have Residue particles as parents All Residue particles that have a Chain particle as an ancestor are considered part of a protein, DNA or RNA, ones without are considered heterogens. The functions produce files that are not valid PDB files, eg only ATOM/HETATM lines are printed for all Atom particles in the hierarchy. Complain if your favorite program can't read them and we might fix it.

void IMP::atom::add_bonds	(	Hierarchy	d,
		const ForceFieldParameters *	ffp = `get_all_atom_CHARMM_parameters()`
	)

Add bonds using definitions from given force field parameters. Note that, at the moment, all added bonds are reported as IMP::Bond::SINGLE, whether or not they actually are.

See Hierarchy See ForceFieldParameters

void IMP::atom::add_dope_score_data ( atom::Hierarchy h )

Add the dope atom types to the atoms in the hierarchy.

Examples:: atom/dope_and_excluded_volume.cpp.

void IMP::atom::add_protein_ligand_score_data ( Hierarchy h )

		FloatKey	radius_key = `FloatKey("radius")`
	)

Add vdW radius from given force field.

See Hierarchy See ForceFieldParameters

Examples:: atom/dope_and_excluded_volume.cpp.

Hierarchy IMP::atom::create_clone ( Hierarchy d )

This method copies the Bond, Bonded, Atom, Residue, and Domain data and the particle name to the new copies in addition to the Hierarchy relationships.

See Hierarchy

Hierarchy IMP::atom::create_clone_one ( Hierarchy d )

This method copies the Atom, Residue, Chain and Domain data and the particle name.

See Hierarchy

IMP::core::RigidBody IMP::atom::create_compatible_rigid_body	(	Hierarchy	h,
		Hierarchy	reference
	)

This method is identical to create_rigid_body() except that the chosen reference frame is aligned with that of reference (which must have exactly the same set of particles). This allows one to make sure the rigid body is equivalent when you have several copies of the same molecule.

See Hierarchy See IMP::core::RigidBody

kernel::Restraint* IMP::atom::create_connectivity_restraint	(	const Selections &	s,
		double	k,
		std::string	name = `"Connectivity%1%"`
	)

Create a restraint connecting the selections.

If one or more of the selections is a rigid body, this will be used to accelerate the computation. See Selection

kernel::Restraint* IMP::atom::create_connectivity_restraint	(	const Selections &	s,
		double	x0,
		double	k,
		std::string	name = `"Connectivity%1%"`
	)

Create a restraint connecting the selections. The particles are allowed to be appart by x0 and still count as connected.

If one or more of the selections is a rigid body, this will be used to accelerate the computation. See Selection

core::XYZR IMP::atom::create_cover	(	const Selection &	s,
		std::string	name = `std::string()`
	)

Create an XYZR particle which always includes the particles in the selection in its bounding volume. If all the particles in the selection are part of the same rigid body, then the created particle is added as part of that rigid body. Otherwise it uses an IMP::core::Cover to maintain the cover property.

Doing this can be a useful way to accelerate computations when it is OK to replace a potential complicated set of geometry represented by the selection with a much simpler one.

See Selection

kernel::Restraint* IMP::atom::create_distance_restraint	(	const Selection &	n0,
		const Selection &	n1,
		double	x0,
		double	k,
		std::string	name = `"Distance%1%"`
	)

Create a distance restraint between the selections.

This restraint applies a harmonic to the minimum distance between a particle in selection n0 and a particle in selection n1.

If one or more of the selections is a rigid body, this will be used to accelerate the computation. See Selection

kernel::Restraint* IMP::atom::create_excluded_volume_restraint	(	const Hierarchies &	hs,
		double	resolution = `-1`
	)

Create an excluded volume restraint for the included molecules. If a value is provided for resolution, then something less than the full resolution representation will be used.

If one or more of the selections is a rigid body, this will be used to accelerate the computation. See Hierarchy

kernel::Restraint* IMP::atom::create_excluded_volume_restraint ( const Selections & s )

Create an excluded volume restraint for a list of selections.

Hierarchy IMP::atom::create_fragment ( const Hierarchies & ps )

A particle representing the fragment is created and initialized.

The Fragment is inserted as a child of the parent (and the particles are removed). The particles become children of the fragment.

Exceptions

ValueException If all the particles do not have the same parent. See Hierarchy

kernel::Restraint* IMP::atom::create_internal_connectivity_restraint	(	const Selection &	s,
		double	k,
		std::string	name = `"Connectivity%1%"`
	)

Create a restraint connecting the selection.

If one or more of the selections is a rigid body, this will be used to accelerate the computation.

See Selection

kernel::Restraint* IMP::atom::create_internal_connectivity_restraint	(	const Selection &	s,
		double	x0,
		double	k,
		std::string	name = `"Connectivity%1%"`
	)

Create a restraint connecting the selection. The particles are allowed to be appart by x0 and still count as connected.

If one or more of the selections is a rigid body, this will be used to accelerate the computation.

See Selection

Hierarchy IMP::atom::create_protein	(	kernel::Model *	m,
		std::string	name,
		double	resolution,
		int	number_of_residues,
		int	first_residue_index = `0`,
		double	volume = `-1`
	)

The coarse grained model is created with a number of spheres based on the resolution and the volume. If the volume is not provided it is estimated based on the number of residues. The protein is created as a molecular hierarchy rooted at p. The leaves are Domain particles with appropriate residue indexes stored and are XYZR particles.

Volume is, as usual, in cubic anstroms.

Currently the function creates a set of balls with radii no greater than resolution which overlap by 20% and have a volume of their union equal to the passed volume.

The coordinates of the balls defining the protein are optimized by default, and have garbage coordinate values.

Warning: create_protein has not been well tested yet: Use with caution and please report any bugs found.

Warning: create_protein has not been stabilized and is likely to change without notice.: See Hierarchy

Hierarchy IMP::atom::create_protein	(	kernel::Model *	m,
		std::string	name,
		double	resolution,
		const Ints	domain_boundaries
	)

Like the former create_protein(), but it enforces domain splits at the provide domain boundairs. The domain boundaries should be the start of the first domain, any boundies, and then one past the end of the last domain.

IMP::core::RigidBody IMP::atom::create_rigid_body	(	const Hierarchies &	h,
		std::string	name = `std::string("created rigid body")`
	)

The rigid body created has all the leaves as members and a member rigid body for each internal node in the tree. The particle created to be the rigid body is returned.

A name can be passed as it is not easy to automatically pick a decent name.

See Also: create_aligned_rigid_body() See Hierarchy See IMP::core::RigidBody

IMP::core::RigidBody IMP::atom::create_rigid_body ( Hierarchy h )

See Also: create_rigid_body(const Hierarchies&)

Hierarchy IMP::atom::create_simplified_along_backbone	(	Hierarchy	input,
		int	num_res,
		bool	keep_detailed = `false`
	)

Simplify every num_res into one particle.

Hierarchy IMP::atom::create_simplified_along_backbone	(	Chain	input,
		const IntRanges &	residue_segments,
		bool	keep_detailed = `false`
	)

Simplify by breaking at the boundaries provided.

void IMP::atom::destroy ( Hierarchy d )

All bonds connecting to these atoms are destroyed as are hierarchy links in the Hierarchy and the particles are removed from the kernel::Model. If this particle has a parent, it is removed from the parent. See Hierarchy

CHARMMParameters* IMP::atom::get_all_atom_CHARMM_parameters ( )

The default CHARMM parameters support normal amino acid and nucleic acid residues and the atoms found in them. To use CHARMM with heterogens or non-standard residues, a different CHARMM parameters file must be used.

See Also: get_heavy_atom_CHARMM_parameters()

Atom IMP::atom::get_atom	(	Residue	rd,
		AtomType	at
	)

The residue must be part of a molecular hierarchy. See Atom See Residue See Hierarchy

algebra::BoundingBoxD<3> IMP::atom::get_bounding_box ( const Hierarchy & h )

This bounding box is that of the highest (in the CS sense of a tree growing down from the root) cut through the tree where each node in the cut has x,y,z, and r. That is, if the root has x,y,z,r then it is the bounding box of that sphere. If only the leaves have radii, it is the bounding box of the leaves. If no such cut exists, the behavior is undefined. See Hierarchy See IMP::algebra::BoundingBoxD

algebra::Sphere3D IMP::atom::get_bounding_sphere ( const Hierarchy & h )

See get_bounding_box() for more details. See Hierarchy

Hierarchies IMP::atom::get_by_type	(	Hierarchy	mhd,
		GetByType	t
	)

Gather all the molecular particles of a certain level in the molecular hierarchy.

Chain IMP::atom::get_chain ( Hierarchy h )

Get the containing chain or Chain() if there is none

Atoms IMP::atom::get_charmm_untyped_atoms ( Hierarchy hierarchy )

Returns: a list of every Atom in the given Hierarchy that is not also a CHARMMAtom.

See Also: remove_charmm_untyped_atoms

FloatPair IMP::atom::get_component_placement_score	(	const core::XYZs &	ref1,
		const core::XYZs &	ref2,
		const core::XYZs &	mdl1,
		const core::XYZs &	mdl2
	)

Parameters

[in]	ref1	The reference placement of the first component represented by XYZ coordinates
[in]	ref2	The reference placement of the second component represented by XYZ coordinates
[in]	mdl1	The modeled placement of the first component represented by XYZ coordinates
[in]	mdl2	The modeled placement of the second component represented by XYZ coordinates

Returns: the function returns (distance score,angle score)

Note: The measure quantifies the difference between the relative placements of two components compared to a reference relative placement. First, the two compared structures are brought into the same frame of reference by superposing the first pair of equivalent domains (ref1 and mdl1). Next, the distance and angle scores are calculated for the second component using placement_score.; see Topf, Lasker et al Structure, 2008 for details

std::string IMP::atom::get_data_path ( std::string file_name )

Each module has its own data directory, so be sure to use the version of this function in the correct module. To read the data file "data_library" that was placed in the data directory of module "mymodule", do something like

std::ifstream in(IMP::mymodule::get_data_path("data_library"));

This will ensure that the code works when IMP is installed or used via the setup_environment.sh script.

double IMP::atom::get_diffusion_angle	(	double	D,
		double	dtfs

Hierarchy IMP::atom::get_next_residue ( Residue rd )

See Residue

Return the residue from the same chain with one higher index, or Hierarchy().

Note: Currently, this function only works if the parent of rd is the chain. This should be fixed later. Ask if you need it.

The return type is Hierarchy since the particle representing the next residue might not be a Residue particle.

Note: The measure quantifies the RMSD between the relative placements of two components compared to a reference relative placement. First, the two compared structures are brought into the same frame of reference by superposing the first pair of equivalent domains (ref1 and mdl1). Next, the RMSD is calculated for the second component; see Lasker et al JMB, 2009 for details
