More information about the software

BVest

BVest has been used in the Australian Sheep industry's LAMBPLAN genetics evaluation program at an across flock level from 1991 until 2002 and is still (2008) used within DPI. It allows preadjustment for known factors (e.g. age, birth type) and formally fits groups (cohorts) and animals.

BVest is designed for routine industry level processing rather than for ad hoc evaluation, in that it requires a fairly complicated parameter file be supplied to control the analysis. It is a batch, or command-line driven, application and does not have a GUI interface.

It has been used to evaluate about 20 traits (counting repeated measures as separate traits) on half a million lambs. It would be suitable for the early stages of developing a national breeding program in a developing country. Support in setting up a BVest application is available on a consultancy basis.

BVest is available for either Windows (32 bit) or Linux (32 or 64 bit). Each downloadable package contains installation instructions, pdf documentation, the original LAMBPLAN parameter file, and a sample dataset, as well as the appropriate executable file.

BVest was written in Fortran 77 by Arthur Gilmour in 1991 (now retired from NSW DPI).

DiGGer

DiGGer is a program to search for optimal experimental designs. It aims to provide a flexible tool for most non-factorial design situations. The user specifies experimental layout and treatment replication levels. Experimental designs with these specifications are optimised under user specified correlation and blocking. DiGGer can find optimal or near-optimal incomplete block designs, row-column designs and spatial (AR or MA) designs.

DiGGer was developed for cereal variety trials with plots in rectangular arrays but can be used for any design which may be nominally described in row and column layouts. Designs may have treatments with unequal replication and may have missing plots. Designs may be optimised for comparisons between groups of treatments.

DiGGer is available as a standalone executable and as an R package. The standalone version runs from an input file or interactively in a command window. The R package generates search specifications which may be modified before the search is run. Functions in R provide search methods for common design types.

Both forms of the program call a Fortran executable to perform the search. The program is written and maintained by Neil Coombes.
