gyration_radius#
- biotite.structure.gyration_radius(array: AtomArray[N] | AtomArrayStack[M, N], masses: ndarray[tuple[N], dtype[floating]] | None = None) floating | ndarray[tuple[M], dtype[floating]][source]#
Compute the radius/radii of gyration of an atom array or stack.
- Parameters:
- arrayAtomArray or AtomArrayStack
The array or stack to calculate the radius/radii of gyration for.
- massesndarray, optional
The masses to use for each atom in the input array. Must have the same length as array. By default, the standard atomic mass for each element is taken.
- Returns:
- massesfloat or ndarray, dtype=float
If array is an
AtomArray, the radius of gyration is returned as single float. If array is anAtomArrayStack, andarraycontaining the radii of gyration for every model is returned.
