WOMBAT
- WOMBAT is a program to facilitate analyses fitting a linear, mixed model via restricted maximum likelihood (REML).
- It is assumed that traits analysed are continuous and have a multivariate normal distribution.
- WOMBAT is set up with quantitative genetic analyses in mind, but is readily applicable in other areas. Its main purpose is the estimation of (co)variance components and the resulting genetic parameters. It is particularly suited to analyses of moderately large to large data sets from livestock improvement programmes, fitting relatively simple models.
- Some more info in : 8WCGALP Software paper (PDF file, 2 pages)
- WOMBAT replaces DFREML which has been withdrawn from distribution at the end of 2005.
- Currently, WOMBAT is available
only as an executable program and only
by downloading from this site.
- Linux : Highly optimised executables, capable of analysing relatively large models and data sets, are available for 32-bit and 64-bit PCs.
- Windows : 32-bit versions are available, but are slower and restricted to smaller analyses than the Linux executables.
- Installation instructions are contained in the user manual (chapter 3).

wombat64.tar.gz
Linux 64-bit version optimised for AMD Opteron; needs a recent Linux distro.

wombat32.tar.gz
Linux 32-bit version , optimised for Pentium IV; good for recent Linux distros.
Size 2.55 MB, 532 downloads (since June 1, 2007), last update: 01/07/08. -
wombat32lf95.tar.gz
Alternative Linux 32-bit version, again optimised for Pentium IV; does not need recent Linux distro, but is limited to analyses using less than 2 GB memory.
Size 977 KB, 299 downloads (since June 1, 2007), last update: 01/07/08. -
wombat32gen.tar.gz
`Generic' Linux 32-bit version, does not assume a Pentium IV processor, like wombat32lf95 otherwise; try this version if the others cause problems.

wombat32check.tar.gz
Linux 'debug' version - use for both 32- and 64-bit systems to compile a bug report (see Chapter 3.3 of the manual).
Size 2.12 MB, 266 downloads (since June 1, 2007), last update: 01/07/08. -

wombatwin2.zip - new & little tested
Windows 32-bit version compiled under MinGW; like wombatwin.tar.gz (Compilation notes) but does not require Cygwin.
Size : 1.14 MB, 1457 downloads (since June 26, 2007), last update: 01/07/08.
Hint: While you can invoke this by "double-clicking" on the file icon, it is recommended that you run this within a DOS window! Click on "Start" and "Run" and type in "CMD"; click again and a window should open. One reason for this is that WOMBAT generates informative screen output (which is especially useful when trying to identify why things don't work) which is lost if the window closes automatically, which is what happens when "double-clicking". Alternative, install MinGW and run in its window.

Note for Windows users: The files in the Example directories are Linux files. Linux and Windows differ in the `end-of-line' codes used. There appear to be no inconsistencies with the Cygwin environment. However, when using wombatwin2.zip `directly' under Windows, you may need to convert the files provided; look for a tool like like `unix2dos' !
