6. Coordinates modules

The coordinates module contains the classes to read and write trajectories. Typically, MDAnalysis recognizes Table of 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 Universe to force the format.

The remaining pages are primarily of interest to developers. Programmers and anyone trying to implement new functionality should first read the Trajectory API.

In particular, all trajectory readers have to be serializable and they should pass all tests available in the MDAnalysisTests.coordinates.base.MultiframeReaderTest or MDAnalysisTests.coordinates.base.BaseReaderTest.
