29 //! Select which atoms to read from a PDB file
30 /** Selector is a general purpose class used to select records from a PDB
31  file. Using descendants of this class one may implement arbitrary
32  selection functions and pass them to PDB reading functions
33  for object selection. Simple selectors can be used to build more complicated
34  ones. Inheritance means "AND" unless otherwise noted (that is, the
35  CAlphaPDBSelector takes all non-alternate C-alphas since it inherits from

429 /** @name PDB Reading
430  \anchor pdb_in
431  The read PDB methods produce a hierarchy that looks as follows:
432  - One Atom per ATOM or HETATM record in the PDB.
433  - All Atom particles have a parent which is a Residue.
434  - All Residue particles have a parent which is a Chain.
435 
436  Waters are currently dropped if they are ATOM records. This can be fixed.
437 
438  The read_pdb() functions should successfully parse all valid PDB files. It
439  can produce warnings on files which are not valid. It will attempt to read
440  such files, but all bets are off.
441 
442  In order to track the provenance of IMP-generated models, the provenance
443  of any PDB files read in here - for example, the PDB id, or detail about
444  a comparative model - needs to also be tracked. This is done using the
445  PDB headers:
446  - Structures stored in the PDB database should keep the standard
447  `HEADER` record stating their PDB ID.
448  - Comparative models generated using MODELLER should include the
449  MODELLER-generated `EXPDTA` and `REMARK` records.
450  - Structures that are trivial modifications of an existing PDB structure
451  or comparative model should use the `TITLE` record to describe the
452  nature of the modification (e.g. rotation and translation) and one of
453  the two following custom `EXPDTA` record formats to point to the original
454  structure:
455  - `EXPDTA DERIVED FROM PDB:1XYZ`
456  - `EXPDTA DERIVED FROM COMPARATIVE MODEL, DOI:x.y/z`
457  - Structures generated from multiple sources (e.g. two structures that
458  have been docked and then concatenated into a single PDB file) are not
459  allowed. Store each constituent structure in its own file and annotate
460  each one with a suitable `EXPDTA` record, as above.
461  Note that while provenance of PDB files is not currently enforced, it
462  likely will be in future IMP releases.
463 
464  When reading PDBs, PDBSelector objects can be used to choose to only process
465  certain record types. See the class documentation for more information.
466  When no PDB selector is supplied for reading, the
467  NonWaterPDBSelector is used.
468
