DESIRE (older version)
|
Written by Brian Kinghorn.
DESCRIPTION
This program is designed to
help you explore the possible outcomes of a breeding program, in terms of
predicted genetic gains for a number of traits. When we set desired gains, this
restricts the possible range of genetic change for other traits. DESIRE is a
dynamic tool to help you surf the n-dimensional (n-trait) space of possible
outcomes from a simple breeding program.
It does this by showing 2-
dimensional slices of this space. The algebra behind DESIRE is largely drawn
from Pim Brascamp’s
paper: Brascamp, E.W. 1984. Selection
indices with constraints. Animal Breeding Abstracts 52:645-654.
In the screen-shot above, yellow ellipses show the outer limits of possible
response. A red ellipse indicates that all points on and within the
ellipse are ‘reachable’ without breaking fixed desires. Some
other features are shown below.

The
closer to the center of the contours that you
click, the less constraint is placed on other traits in the objective |
Click
‘Econ Lines’ to show lines of equal economic merit. The red line
has the highest economic value. |
Click
‘Single trait’ to get these green dots that show the direct and
correlated responses to single-trait selection. |

DESIRE has been written to
handle any number of traits, but more that about 10 traits is not recommended.
All traits are in the breeding objective – although they can be
effectively excluded by setting their economic weights to zero. Any of the
traits can be declared as measured and part of the selection index.

Downloading
DESIRE
NB. Desire is also integrated
as a module within GENUP. This stand-alone
version has no extra function, but takes up less room.
Download
desire.zip and
save it in an empty directory on your hard disk (you can delete this directory
and all its files after installation). If you have a capable
program such as WinZIP, you can execute SETUP.EXE
directly. Otherwise unzip the file. If you do not have an unzipper, you can download pkunzip.exe, into the same directory, and
then run:
pkunzip desire.zip at the DOS
prompt.
Three files will be produced. Run the file SETUP.EXE and follow instructions.
[NB. You may be told that some system files need updating. This is done
by Microsoft, whose recent VB6 compiler was used for making DESIRE. In
this case you will need to re-run SETUP.EXE after updating your system
files. If you have a problem, go to http://support.microsoft.com/default.aspx?scid=kb;EN;q191096].
After installation, a start menu item which runs the installed program will
result.
Use the program's Help menu to get started.
Good Luck!
