About Nicer: NICER is a program for automatic determination of a number of parameters that allow evaluation of the quality of inferred phylogenies (evolutionary trees). It was originally developed by Dr. Lester M. Shulman and Dr. Jaime Prilusky for evaluating whether or not a cluster of vaccine-derived polioviruses evolved as part of a single epidemiological event.
