the cookbook. or referencing the cookbook The cookbook is also available as a, which makes easier to print it as a single document. Introduction ASReml is a very powerful statistical software developed by from, with support from an international team of leading statisticians. It is specifically designed for fitting mixed models for large datasets, with unmatched model flexibility and high speed. It is far faster than, and similar software. I have a few reasons why I think that ASReml is.
ASReml’s manual is the source of all knowledge, with over 200 pages. That is a bit of an overstatement, but it is certainly exhaustive and sometimes daunting. One of the problems when you start using ASReml is how do I start? How do I setup my models the way I used to in / / / etc?
I have trees, no animals, what do I do? I have spent a long time learning how to fit models with the software, and I have I decided to make some of the information available in this site, in case it can be of some use for you. How do I obtain ASReml? ASReml is a commercial product.
Trial (30 days) versions can be obtained from web site. The page provides full instructions for getting the software and the manual. There are several versions or ways to access ASReml:.
It can be used as a console (terminal) program, writing all the code in a text editor and then using the command line to submit the job. This is the oldest way, and the one that I have used the most. It can also be used as a windows program with its own editor (at least under MS Windows).
I have never used it this way, which I consider mostly a hassle. It can be used as a library or module called from or S+.
This has the convenience of using a general purpose statistics software for data preparation, plotting and further processing, combined with the power of ASReml. In this case ASReml acts as an alternative to the lme library, with efficient processing of data sets with a pedigree. This is the way I am moving towards at the moment. I will add more information on using ASReml from R during 2009.
When buying a license the user gets access to all three versions. The core FORTRAN functions of ASReml are also the engine of the REML procedure in GenStat. However, this site does not provide any information on using that software.
Getting help Besides the manual, the cookbook and other web sites, there is now a. Please do not contact me for help with your analyses, as I do no have time for that. Using a decent text editor To run an ASReml job you need to write an ASReml command file (the file with a.as extension). Hence, one of the first things you should get is a decent text editor.
If you work in MS Windows you already now that Notepad is hopeless, and probably you do not want to spend any money. There are plenty of free or shareware editors around, but I recommend using, which is a free ‘ASREml aware’ programming text editor.
There are a few instructions to for ASReml use. People at use the commercial editor Ultraedit for preparing ASReml code and they have developed a syntax highlighter for it. There are some instructions to for this purpose. Can I use ASReml in my mac? Starting in December 2009, ASReml is natively supported in OS X (both 32 and 64 Bits).
However, there is not yet an official asreml-r version; there is, however, an experimental asreml-r version. In addition, there are two other ways of running ASReml on Intel-based Apple computers (Macbook, Macbook Pro, Mac Pro and new mac minis and imacs):. Use to boot your mac in one of the operating systems supported by ASReml. For example, you could boot using Windows XP and the mac would essentially be a windows machine. Use a virtualization machine, for example, to have multiple operating systems running on your mac. In this case there is a windows containing a session of Windows (or Linux, or whatever) running inside OS-X.
This is how I run ASReml in my Macbook Pro. I have tried this only with the Windows version of ASReml, but I assume that it would work the same with the Unix versions. I now prefer dual booting, because the system is much more reponsive (and a mac is a very good windows machine).
If you go for the second option be aware that you will require plenty of RAM; essentially you will be running two operating systems at once. With 1GB my system felt sluggish but it worked quite well with 2GB and higher. The recipes Here is what you are really looking for!
Below there are recipes to run the following types of analyses, the first link is for ASReml console (or classic) and the second link is for asreml-R:. Basic structure.
Equation model description. including:. Some basic models. Equivalent models. Diallels.
Clonal data. Multiple site, single trait. (both versions).
This version offers a more unified framework and extended functionality for LMM analysis, particularly for large and complex data sets. New features with Version 4 include:. for model specification:. rcov becomes residual and direct sum structures for residual models with data partitioned into sections to which separate variance structures are applied are now logically specified using a dsum function.
rarely used options are now listed externally to the model call in a new asreml.options function. a more unified framework for related arguments in the call to asremland the output object, e.g.
