hPDB: Protein Databank file format library

[ bioinformatics-, bsd3, library ] [ Propose Tags ] [ Report a vulnerability ]

Protein Data Bank file format is a most popular format for holding biological macromolecular data.

This is a very fast sequential parser:

  • below 7s for the largest entry in PDB - 1HTQ which is over 70MB - as compared with

  • 11s of RASMOL 2.7.5,

  • or 2m15s of BioPython with Python 2.6 interpreter.

In its parallel incarnation it is most probably the fastest parser for PDB format.

It is aimed to not only deliver event-based interface, but also a high-level data structure for manipulating data in spirit of BioPython's PDB parser.

Flags

Automatic Flags
NameDescriptionDefault
have-mmap

Use mmap to read input faster.

Enabled
have-sse2

Use -msse2 for faster code.

Enabled
have-text-format

Do not use text-format, since it may require double-conversion and thus linking of libstdc++ which may break compilation due to GHC bug #5289:

http://ghc.haskell.org/trac/ghc/ticket/5289

Disabled

Use -f <flag> to enable a flag, or -f -<flag> to disable that flag. More info

hPDB

Haskell PDB file format parser.

Build Status Hackage Hackage Dependencies

Protein Data Bank file format is a most popular format for holding biomolecule data.

This is a very fast parser:

  • below 7s for the largest entry in PDB - 1HTQ which is over 70MB
  • as compared with 11s of RASMOL 2.7.5,
  • or 2m15s of BioPython with Python 2.6 interpreter.

It is aimed to not only deliver event-based interface, but also a high-level data structure for manipulating data in spirit of BioPython's PDB parser.

Details on official releases are on Hackage

This package is also a part of Stackage - a stable subset of Hackage.

Projects for the future:

Please let me know if you would be willing to push the project further.

In particular one may considering these features:

  • Implement basic spatial operations of RMS superposition (with SVD), affine transform on a substructure.
  • Use lens to facilitate access to the data structures.
    • torsion angles within protein/RNA chain.
  • Add Octree to the default data structure (with automatic update.)
  • Migrate out of text-format, since it gives portability trouble, and slows things down when printing.
  • Write a combinator library for generic fast parsing.
  • Checking whether GHC 7.8 improved efficiency of fixed point arithmetic, since PDB coordinates have dynamic range of just ~2^20 bits, with smallest step of 0.001.
  • Class-based wrappers showing Structure-Model-Chain-Residue-Atom interface with possible wrapping of Repa/Accelerate arrays for fast computation.

Please ask me any questions on Gitter.
