Pedigree Display

The program reads your simple data file and displays the full pedigree structure on the screen. Each animal is represented by its identity, or its name, or by its value for any of the traits in the data file. You can display a large pedigree of thousands of animals all on the screen at the one time. Data are overlapped on the screen for such large pedigrees, but in one mode an individual's information is highlighted as the mouse cursor passes over. You can ask to find an animal(s) by identity, or by merit or merit range for a given trait.

A single click changes between fields in the data file, or displays just relatives (of chosen degree) of the animal clicked. With one more click you can then organise the pedigree picture to be most clear for just those animals. Animals of high merit can be shaded more brightly for numerical fields, giving quick access to those with high merit. You can also zoom into interesting parts of the pedigree (as in the example above), change the font displaying data, check for logical errors, alter the display of pedigree links and make other manipulations to give a suitable display.

Inbreeding coefficients and BLUP estimates of breeding value can be calculated and added to the list of displayable data. The program can be useful for navigating around a pedigreed data set to get a feel for its structure and any problems it might contain. Embryo transfer matings are usually easy to spot. By shading fields and possibly sorting horizontally, phenotypic and EBV trends can be quite noticeable.

Mate Selection

A key new feature is the Mate Selection module MateSel, which brings together the tasks of selecting which individuals to select as parents, and the pattern of mate allocation that should be used.  This is done in a manner that gives appropriate balance in achieving diverse objectives relating, for example, to genetic change in key traits, managing genetic diversity, paying attention to progeny inbreeding and progeny trait distributions, which individuals to collect semen or oocytes/embryos from, and keeping operating costs at a desired level.

[Note: Some users may see “Navigation to the webpage was canceled” in the right-hand pane after downloading.  This is a safety feature for downloaded *.chm files.  If this happens, you need to install the full application and then open the Helpfile from the Help menu.]

Pedigree Viewer runs under Microsoft Windows XP/Vista.  No version is available for Macintosh or Linux operating systems.

Recent version changes …



This is the last version made in the old Visual Basic language.  It can read input files made in the Gedcom format used for human pedigree data.   Click here for this version.



Major upgrade to Pedigree Viewer, made in VB.NET plus Fortran, and significantly enhanced.



Pedigree Pruning added   Retain N generations above nominated candidates, prune uninformative individuals, etc.     Also: "." taken as missing code for parents. *.DAT files accepted as pedigree files.  Missing header warning.



‘Display Fields’ in View menu.  Show inbreeding coefficients automatically.  PedFind: 'Reset display' and clarify.   MateSel: Simpler display.  Better targeting above 45 degrees. Print matings to NotePad.      Bug Fixes: Projection to 0 degrees. Openfile listings.  DLL path issue "An endfile record ..."



Now runs inbreeding/BLUP/MateSel under 64-bit Windows (x86 compile to match with 32-bit DLL's).    Missing text filed value set to "."



Special features added: TierInfo, eg. to force chronological ordering of tiers displayed; ShowMe to optionally hide nominated individuals; and Annotate to optionally annotate specific pedigree links.   Save a part-pedigree in its own file.  Display last optimised pedigree.  Revisit last opened file directory. (6.4a: incorrect dll bug fixed.  6.4b: Fix "no parents" bug. Clean up HighLight Target. 6.4c: Fix bug: "When selecting a bisexual parent all offspring are colored as self matings".).  6.4d Correct MateSell.dll file resinstated (since 6.4a), was a test vesion aiming 2 generations ahead and giving less response in generation 1.  Data file requirements for annotation of sex corrected in the Help file.



Grouping constraints feature added in MateSel (see

CSV files can be read in as pedigree files. 

Coan.txt is now comma delimited for easy import to Excel.

Warning to calculate inbreeding coefficients before saving sequential ID file.

Bug fixed: TierInfo record="."


Click on   You can choose to “Open” this file and execute “setup.exe” directly when it appears.  Otherwise, choose “Save”, and save “” in an empty directory on your hard disk (you can delete this directory and all its files after installation). Then double-click “” in your chosen directory, double-click on “setup.exe” and follow instructions.  [If you have an older system and find that you do not have an unzipper, you can download pkunzip.exe, into the same directory, and then run:  pkunzip  at the DOS prompt.]

[NOTE:  This setup uses ClickOnce Deployment, which is possible because Pedigree Viewer is a simple, well-behaved application that does not, for example, write to the system registry.  It does not install in the Program Files folder, but somewhere under C:\Users\<username>\AppData\Local\Apps\...    To locate this directory after the install:  In the dialog box to open a new pedigree file, right-click on the folder textbox and select “Copy Address”.  Then paste that into the address box of Windows Explorer to open the directory in which Pedigree.Exe resides.]

You will find a shortcut to the program at the Start Menu, under the Pedigree Viewer folder.  You might choose to copy this shortcut to your desktop.   Once PV is launched, use the program's Help menu to get started.

Good Luck!
