Any program capable of rotation function calculations should
work (i.e. Amore, ALMN, Polarrfn with the CCP4 package all use
variations of the fast rotation function, MERLOT, PROTEIN and
I'm sure there are others).  It is often convinient to look at
your answers in polar angles as these allow one to relate the
NCS elements easily.
