opencadd.structure.core.Structure.coord
- property Structure.coord
Reference to current timestep and coordinates of universe.
The raw trajectory coordinates are
Universe.coord.positions
, represented as anumpy.float32
array.Because
coord
is a reference to aTimestep
, it changes its contents while one is stepping through the trajectory.Note
In order to access the coordinates it is better to use the
AtomGroup.positions()
method; for instance, all coordinates of the Universe as a numpy array:Universe.atoms.positions()
.
