.. Contains the formatted docstrings from the coordinates modules located in 'mdanalysis/MDAnalysis/coordinates' .. _Coordinates: ************************** Coordinates modules ************************** The coordinates module contains the classes to read and write trajectories. Typically, MDAnalysis recognizes :ref:`Supported coordinate formats` by the file extension and hence most users probably do not need to concern themselves with classes and functions described here. However, if MDAnalysis fails to recognize a coordinate file then the user can provide the format in the keyword argument *format* to :class:`~MDAnalysis.core.universe.Universe` to force the format. .. rubric:: Coordinate formats .. toctree:: :maxdepth: 1 coordinates/init coordinates/CRD coordinates/DCD coordinates/DLPoly coordinates/DMS coordinates/GMS coordinates/GSD coordinates/GRO coordinates/H5MD coordinates/INPCRD coordinates/LAMMPS coordinates/MMTF coordinates/MOL2 coordinates/NAMDBIN coordinates/PDB coordinates/PDBQT coordinates/PQR coordinates/TNG coordinates/TRC coordinates/TRJ coordinates/TRR coordinates/TRZ coordinates/TXYZ coordinates/XTC coordinates/XYZ coordinates/FHIAIMS coordinates/memory coordinates/chemfiles coordinates/null .. rubric:: Coordinate core modules The remaining pages are primarily of interest to developers.
