PyPedal was initially written to support the author's dissertation research while at Louisiana State University, Baton Rouge (http://www.lsu.edu/). The initial development was supported in part by a grant from The Seeing Eye, Inc., Morristown, NJ, USA. It lay fallow for some time but has recently come under active development again. This is due in part to a request from colleagues at the University of Minnesota that led to the inclusion of new functionality in PyPedal. The author wishes to thank Paul VanRaden for very helpful suggestions for improving the ability of PyPedal to handle certain computations in large pedigrees. Additional feedback in the form of bug reports, feature requests, and discussion of computing strategies was provided by Dan Cieslak, Bradley J. Heins (University of Minnesota-Twin Cities), Edward H. Hagen (Institute for Theoretical Biology, Humboldt-Universität zu Berlin), Kathy Hanford (University of Nebraska, Lincoln), Thomas Kelly (Department of Animal and Poultry Science, University of Guelph), Thomas von Hassell, Gianluca Saba, and Ken Severin (University of Alaska - Fairbanks). Gregor Gorjanc has written a blog entry describing http://ggorjan.blogspot.com/2007/04/installing-pypedal-under-debian.htmlhow to install PyPedal on Debian Linux. Fernando Perez posted a LaTeXpreamble to the NumPy listserver that dramatically improved the PDF version of This Manual.
The Newfoundland pedigree presented in Figure 9.4 was taken from the NewFoundland Dog database (http://www.newfoundlanddog-database.net/en/) and is used with permission.
The pedigree of European royalty used in the GEDCOM discussion (Appendix B), http://www.genealogyforum.com/gedcom/gedcom1/ged3.htmged3.ged, was taken from the Genealogy Forum website (http://www.genealogyforum.com/). It is believed to be in the public domain, and is used with the knowledge of the website administrators.
