Input methods and objects

iotbx.pdb.input(file_name=None, source_info=<class 'iotbx.pdb.Please_pass_string_or_None'>, lines=None, pdb_id=None, raise_sorry_if_format_error=False)

Main input method for both PDB and mmCIF files; will automatically determine the actual format and return the appropriate data type.

Parameters:
  • file_name (path to PDB or mmCIF file)

  • source_info (string describing source of input (e.g. file name))

  • lines (flex.std_string array of input lines)

  • pdb_id (PDB ID to automatically retrieve from local mirror)

  • raise_sorry_if_format_error (re-raise any low-level parser errors as a) – libtbx.utils.Sorry exception instance for clean user feedback

Returns:

  • An object representing the result of parsing, including an array of atom

  • objects; the actual class will differ depending on the input format. Much of

  • the API will be the same in either case.

class iotbx.pdb.ext.input

Bases: instance

This class parses PDB format, including non-ATOM records. Atom objects will be created as part of the parsing, but the full PDB hierarchy object requires calling the construct_hierarchy() method.

as_pdb_string(crystal_symmetry=<libtbx.AutoType object>, cryst1_z=<libtbx.AutoType object>, write_scale_records=True, append_end=False, atom_hetatm=True, sigatm=True, anisou=True, siguij=True, cstringio=None, link_records=<libtbx.AutoType object>, return_cstringio=<libtbx.AutoType object>)

Generate standard PDB format. Will use built-in crystal symmetry if available.

Collect link records from PDB file

extract_authors()
extract_connectivity()

Parse CONECT records and extract the indices of bonded atoms. Returns a scitbx.array_family.shared.stl_set_unsigned object corresponding to the atoms array, with each element being the list of indices of bonded atoms (if any). If no CONECT records are found, returns None.

Note that the ordering of atoms may be altered by construct_hierarchy(), so this method should probably be called after the hierarchy is made.

PDB hierarchy objects

class iotbx.pdb.hierarchy.root

Bases: instance

Root node of the PDB hierarchy object. This is returned by the method construct_hierarchy() of the PDB/mmCIF input objects, but it may also be created programatically. Note that it does not contain any reference to crystal symmetry or source scattering information, meaning that in practice it must often be tracked alongside an equivalent cctbx.xray.structure object. Pickling is supported, simply by writing out and reading back the PDB-format representation of the hierarchy.

Examples

>>> hierarchy = iotbx.pdb.hierarchy.root()
adopt_xray_structure(xray_structure)

Apply the current (refined) atomic parameters from the cctbx.xray.structure object to the atoms in the PDB hierarchy.

as_dict_of_chain_id_resseq_as_int_residue_names()
as_forward_compatible_hierarchy(conversion_info=None)

Convert a standard hierarchy to a forward_compatible_hierarchy

:params conversion_info

:returns pdb_hierarchy with chain ID and residue names converted to

strings compatible with PDB formatting. Returned hierarchy is a deep_copy and contains the attribute _conversion_info with the conversion_info used

Typical use: running a method with cmd_text (text commands) and supplying

a hierarchy (or string from it). Convert the hierarchy and the cmd_text, run the method, convert the results back:

# Convert the hierarchy to forward compatible ph_fc = ph.as_forward_compatible_hierarchy()

# Convert any commands. Can be done one word at a time also cmd_text_fc = ph_fc.convert_multi_word_text_to_forward_compatible(cmd_text)

# Run the method with converted hierarchy and commands result = do_something(ph = ph_fc, command_text = cmd_text_fc)

# Convert back any resulting hierarchy new_ph = result.ph.forward_compatible_hierarchy_as_standard(

conversion_info = ph_fc.conversion_info())

# Convert back any words in the results that referred to converted # items. Keys are chain_id and resname new_result_items = [] for result_item,key in zip(results.text_words, results.text_keys):

new_result_item = ph_fc.conversion_info(). get_full_text_from_forward_compatible_pdb_text(key = key,

forward_compatible_pdb_text = result_item)

new_result_items.append(new_result_item)

as_forward_compatible_string(**kw)

as_model_manager(crystal_symmetry, unit_cell_crystal_symmetry=None, shift_cart=None)

Returns simple version of model object based on this hierarchy Expects but does not require crystal_symmetry. Optional unit_cell_crystal_symmetry and shift_cart.

Note that if crystal_symmetry is not supplied, this uses a text representation of the hierarchy so that values for xyz, occ, b, and crystal_symmetry are all rounded.

as_pdb_input(crystal_symmetry=None, segid_as_auth_segid=True)

Generate corresponding pdb.input object. Note that this uses a text representation of the hierarchy so that values for xyz, occ, b, and crystal_symmetry are all rounded.

as_pdb_or_mmcif_string(target_format=None, segid_as_auth_segid=True, remark_section=None, **kw)
Shortcut for pdb_or_mmcif_string_info with write_file=False, returning

only the string representing this hierarchy. The string may be in PDB or mmCIF format, with target_format used if it is feasible.

Method to allow shifting from general writing as pdb to writing as mmcif, with the change in two places (here and model.py) Use default of segid_as_auth_segid=True here (different than

as_mmcif_string())

Parameters:
  • target_format – desired output format, pdb or mmcif

  • segid_as_auth_segid – use the segid in hierarchy as the auth_segid in mmcif output

Shortcut for pdb_or_mmcif_string_info with write_file=True, returning

only the name of the file that is written. The file may be written in PDB or mmCIF format, with target_format used if feasible.

Method to allow shifting from general writing as pdb to writing as mmcif, with the change in two places (here and model.py) Use default of segid_as_auth_segid=True here (different than

as_mmcif_string())

Parameters:
  • target_format – desired output format, pdb or mmcif

  • target_filename – desired output file name, to be modified to match the output format

  • data_manager – data_manager to write files

  • overwrite – parameter to set overwrite=True in data_manager if True

  • segid_as_auth_segid – use the segid in hierarchy as the auth_segid in mmcif output

  • remark_section – if supplied and format is pdb, add this text

  • **kw

    any keywords suitable for as_pdb_string() and as_mmcif_string()

:returns name of file that is written

class iotbx.pdb.hierarchy.model

Bases: instance

Class representing MODEL blocks in a PDB file (or equivalent mmCIF). There will always be at least one of these in a hierarchy root extracted from a PDB file even if no MODEL records are present.

Example

>>> hierarchy = iotbx.pdb.hierarchy.root()
>>> model = iotbx.pdb.hierarchy.model(id="1")
>>> hierarchy.append_model(model)
>>> model = hierarchy.only_model()

Bases: instance

The basic unit of the PDB hierarchy (or the PDB input object in general), representing a single point scatterer corresponding to an ATOM or HETATM record in PDB format (plus associated ANISOU or related records if present). Note that this does not directly store attributes of higher-level entities whose identity is also recorded in ATOM records, such as the chain ID or residue name. These may be retrieved either by walking up the hierarchy starting with atom.parent(), or by calling atom.fetch_labels().
