.. _MAXCI: MAXCI ===== The maximum number of configurations in an :ref:`INDO` calculation. **SYNTAX:** ``MAXCI=n`` The maximum number is set to :math:`n`. Configurations are sorted by energy, and the :math:`n` lowest-energy excitations are retained. By default, this value is set to 2000. It can be increased to :math:`\approx 7000` before running into memory constraints.
