NRI scores and the precision and recall components for various scenarios.

Scenario	P	R	Global NRI
A neuron is split into two pieces with equal number of synapses	1.00	0.50	0.67
A neuron is split into three pieces with equal number of synapses	1.00	0.33	0.50
Two whole neurons are merged	0.50	1.00	0.67
Three whole neurons are merged	0.33	1.00	0.50
One neuron in a network of 10 neurons is split into 9 pieces and each piece is merged with one of the other 9 neurons	0.82	0.91	0.86
In a network of neurons, 20% of synapses on each neuron are deleted	1.00	0.64	0.78

Scores are intuitively commensurate with the magnitudes and types of reconstruction errors.
