This exception is raised in the following scenarios: * Raised when a :class:`~MDAnalysis.core.topologyattrs.TopologyAttr` (e.g., bonds, charges) is not present in the data. * Raised when data is missing in an analysis class because the `run()` method has not been called, e.g. :class:`~MDAnalysis.analysis.polymer.PersistenceLength`. * Raised when timestep data is missing, such as positions, velocities, or forces. * Raised in the `nojump` transformation if there is no box information in the universe. This exception should not be raised in cases where arrays have zero width, or AtomGroups are empty. .. versionchanged:: 1.0.0 Now a subclass of AttributeError as well as ValueError Nrr r r r r #sr r ceZdZdZdS)ApplicationErrorzRaised when an external application failed.
