openpathsampling.collectivevariable.CoordinateGeneratorCV

class openpathsampling.collectivevariable.CoordinateGeneratorCV(name, generator, cv_requires_lists=False, cv_wrap_numpy_array=False, cv_scalarize_numpy_singletons=False, **kwargs)

Turn a callable class or function generating a callable object into a CV

The class instance will be called with snapshots. The instance itself will be created using the given **kwargs.

__init__(name, generator, cv_requires_lists=False, cv_wrap_numpy_array=False, cv_scalarize_numpy_singletons=False, **kwargs)

Parameters

• name –

• generator –

• cv_requires_lists –

• cv_wrap_numpy_array –

• cv_scalarize_numpy_singletons –

• **kwargs –

Notes

Right now you cannot store user-defined classes. Only classes from external packages can be used.
