Pedfiddler is a set of programs to manipulate pedigree graphs. It can be used as a stand-alone version of the graphics facilities found in Pedpack. However, Pedfiddler is not fully compatible with Pedpack because it is not intended for analysis, but graphical purposes only.

The main difference between Pedfiddler and Pedpack is the `pedc' files. In Pedfiddler the inbreeding information is replaced with four columns (three for the colors in RGB format, and the last one for labels, so it does not require an alias file). Other enhancements include a new GUI and an upgrade of the routines used to generate EPS files.

The programs in this package are:

• editpedc
• index2pedc
• list2pedc
• pedc2ps
• pedcsharp
• pfiddler

Pedfiddler 0.3 includes the additional program

• mkgg

Pedfiddler has been developed at McGill University by J C. Loredo-Osti and Kenneth Morgan (ken@bagel.epi.mcgill.ca) and supported by grants from the Canadian Genetic Diseases Network and the Mathematics of Information and Technology and Complex Systems Network (Canadian Networks of Centres of Excellence program). Dr. Loredo-Osti is now at the Memorial University of Newfoundland (loredoos@math.mun.ca.

The Mac OSX Universal Binaries of Sept 2008 were made by Dr. Michael Li of University of Minnesota (nali@umn.edu).
