Functionality for loading, creating, manipulating and scoring atomic structures.
Molecules and collections of molecules are represented using Hierarchy particles. Whenever possible, one should prefer to use IMP::atom::Selection and related helper functions to manipulate molecules as that provides a simple and biologically relevant way of describing parts of molecules of interest.
The name "residue index" is used to refer to the index of the residue in the conventional description of the protein, as opposed to its index among the set of residues which are found in the current molecule. The same concept is known as the "residue number" in PDB files. This index is not necessarily unique within a Chain; however, the combination of the residue index and insertion code should be.
Several helper programs are also provided. They all take the name of the PDB file as the first argument:
Check a PDB file for problems.
Score ligand poses. To score the poses, use the ligand_score command line tool.
Two different scoring files are provided:
The rank score is used by default.
They are both located in the IMP.atom data directory. This directory is available within IMP python scripts via the IMP::atom::get_data_path() function. From the command line, the files can be found at build/data/atom if IMP is not installed or something like /usr/share/imp/data/atom if it is installed.
Score ligand poses from docking output. Like the ligand_score tool, this scores ligand poses, but unlike that tool, it does not score the current pose; instead, it scores each pose corresponding to a transformation in a docking program output file. The transformation file has a simple format (it is a subset of the PatchDock output); the 7 space-separated columns should be the transformation number followed by the ligand translation and rotation.

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. | |

PDB Reading | |
The read PDB methods produce a hierarchy that looks as follows:
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. In order to track the provenance of IMP-generated models, the provenance of any PDB files read in here - for example, the PDB id, or detail about a comparative model - needs to also be tracked. This is done using the PDB headers:
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 PDB expects a Hierarchy that looks as follows: 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. | |

| Element | e | ||
| ) |
| 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.
| void IMP::atom::add_dope_score_data | ( | atom::Hierarchy | h | ) |
Add the dope atom types to the atoms in the hierarchy.
| void IMP::atom::add_loop_statistical_score_data | ( | atom::Hierarchy | h | ) |

||
| ) |
Add vdW radius from given force field.
| IMP::core::RigidBody IMP::atom::create_compatible_rigid_body | ( | Hierarchy | h, |
| Hierarchy | reference | ||
| ) |
Rigidify a molecule or collection of molecules.
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.
| 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.
| 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 apart 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.
| 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 potentially complicated set of geometries represented by the selection with a much simpler one.
| 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.
| 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.
| Restraint* IMP::atom::create_excluded_volume_restraint | ( | const Selections & | s | ) |
Create an excluded volume restraint for a list of selections.
| 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.
| 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 apart 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.
| Hierarchy IMP::atom::create_protein | ( | Model * | m, |
| std::string | name, | ||
| double | target_radius, | ||
| int | number_of_residues, | ||
| int | first_residue_index = 0, |
||
| double | volume = -1 |
||
| ) |
Create a coarse grained molecule.
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 angstroms.
Currently the function creates a set of balls with radii no greater than target_radius 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 not optimized by default, and have garbage coordinate values.
| Hierarchy IMP::atom::create_protein | ( | Model * | m, |
| std::string | name, | ||
| double | target_radius, | ||
| const Ints | domain_boundaries | ||
| ) |
Like the former create_protein(), but it enforces domain splits at the provided domain boundaries. The domain boundaries should be the start of the first domain, any boundaries, 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") |
||
| ) |
Rigidify a molecule or collection of molecules.
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.
| IMP::core::RigidBody IMP::atom::create_rigid_body | ( | Hierarchy | h | ) |
| 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.
| Hierarchy IMP::atom::create_simplified_assembly_from_volume | ( | Hierarchy | h, |
| double | resolution | ||
| ) |
Create a new hierarchy that approximates the volume occupied by the old one.
This function is like create_simplified_from_volume() except that the result is divided into Chain and Molecule bits. It assumes that all geometry is rooted under a chain or a molecule.
| Hierarchy IMP::atom::create_simplified_from_volume | ( | Hierarchy | h, |
| double | resolution | ||
| ) |
Create a new hierarchy that approximates the volume occupied by the old one.
The new hierarchy will contain a number of Fragment particles whose surface (and hence volume) approximates the input hierarchy in the sense of IMP::algebra::get_simplified_from_volume().
The resulting representation has approximately the desired resolution in the sense of get_resolution().
Residue indexes are assigned to the created Fragments from the original residue indexes, and particles containing adjacent residues are connected by bonds.
| 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.

| AtomType | at | ||
| ) |
| bool IMP::atom::get_atom_type_exists | ( | std::string | name | ) |
Return true if that atom type already exists.

| int IMP::atom::get_copy_index | ( | Hierarchy | h | ) |
Walk up the hierarchy to find the current copy index.
