CodeEntropy.trajectory.source module¶

MDAnalysis frame access boundary.

class CodeEntropy.trajectory.source.FrameSource(universe: Any, selection: FrameSelection)[source]¶

Bases: object

Single owner of selected MDAnalysis trajectory frame access.

Variables:

universe (Any) – Active MDAnalysis Universe used for analysis.
selection (CodeEntropy.trajectory.frames.FrameSelection) – Absolute trajectory frame selection.

iter_indices() → Iterator[int][source]¶: Yield absolute selected trajectory frame indices.

iter_pairs() → Iterator[tuple[int, int]][source]¶: Yield (local_i, absolute_frame_index) pairs.

iter_source_indices() → Iterator[int][source]¶: Yield absolute selected trajectory frame indices.

seek(frame_index: int) → Any[source]¶

Move the universe to an absolute trajectory frame.

Parameters:: frame_index – Absolute source-trajectory frame index.
Returns:: The MDAnalysis timestep for the selected frame.
