The following is a complete list of the current differences between Pedigree Explorer and Pedigree Publisher - note this will possibly change very quickly as more features are added to PedPub. Note Hawkeye and HerdKeeper are respectively the horse and goat/sheep/cattle versions of BreedMate and they can be purchased with the Lite, Pro or PedX options..

Case sensitive PedX is not case sensitive so it will match up a sire called FRED with a record named fred. PedPub is case sensitive. This means that there may be some pedigrees which will show in PedX but not in PedPub. This is however easily fixed by correcting whichever name, sire or dam has the incorrect casing then copy pasting to the other occurrences or just use SEARCH-Find Replace.

Exclusive features Descendants chart, Breed Planner. Circular pedigrees, advanced 7G A4 (US Letter) and 8G A3 (Folio) pedigrees.
Foreign characters PedX has limited support for these. PedPub fully supports foreign character sets like European, Polish, Czech, Japanese, Chinese, Korean etc.
Create PDF pedigrees If you want PDF pedigrees then you have to install a PDF print driver and print to it. Directly generates PDF files. In particular it will generate a single PDF for the Pedigree Chart which can then be sent to printers for direct printing at large format sizes such as A0, A1, A2, A3 etc.

Inbreeding calculation on all records PedX can do this to a settable number of generations but it only outputs COI. PedPub can do this to a settable number of generations plus outputs number of ancestors, siblings, offspring, COI, AVK. Results can be saved to a CSV file.
