The fourth PyPedal class, NewAMatrix, is used to manipulate numerator relationship matrices (NRM). When working with large pedigrees it can take a long time to compute the elements of a NRM, and having an easy way to save and restore them is quite convenient.
PyPedal also provides LightAnimal and SimAnimal objects. LightAnimals are intended for use with the graph theoretic routines provided in pyp_network and lack many of the attributes of NewAnimal objects, such as names, breeds, and alleleotypes. SimAnimals are intended for internal use only by the pedigree simulation routines.
A detailed explanation of each class is provided in Chapter 6.See About this document... for information on suggesting changes.
