yapp is a program that includes a set of utilities to work on high density genetic data in pedigrees. It is similar to other existing softwares such as LINKPHASE, FIMPUTE, AlphaPhase ... . I developed it for my own research to have a tool that is opensource and that I can tweak to my own needs.

If you find it useful for you, drop me a note (e.g. on twitter @BertrandServin). If you want to contribute ideas or code, you are welcome if you know python :)

yapp and its utilities implement some models and methods that have been invented by other people. If you use yapp it is important that you acknowledge their work by citing the appropriate references. These will depend on the way you use the software, see the documentation.
