MTDFREML Sample Analyses

The sample.exe file contains two example analyses, a single and a two trait analysis. Both analyses use the mouse data distributed by Karin Meyer with her DFREML programs.

The analyses are useful for two purposes. First, they can be used by new users to run an analysis and become familiar with the steps involved in running the MTDFREML programs. It may be easiest in this case to print the input files (mousenrm.in, mouseprp.in, and mouserun.in for each analysis) and work through each analysis interactively. It is important to make certain that the analyses are run in a different subdirectory than where the files were uncompressed from sample.exe so that you can check to be sure that the results match.

The second use of the analyses are to confirm that MTDFREML is running correctly on your system. The user can simply redirect the console input and output to files using the nrm.bat, prep.bat, and run.bat files for a unix or pc based system. The commands may need minor modification depending on the compiler that you are using. Again, make certain that the analyses are run in a different subdirectory than where the files were uncompressed so that you can check to be sure that the results match.

It is important to keep the two analyses separate, as there are many duplicate file names in the directories (all of the MTDF## files are created in both analyses). In order to to keep the analyses separate, they were stored in two separate directories, one_trt and two_trt. To restore the directories correctly use the command sample -d [drive:\path]. This will create the directories and place the files in the correct place, The two subdirectories each contain a complete analysis (all the MTDF## output files) with the output usually sent to the screen in an .out file (e.g., mousenrm.out contains the console information from MTDFNRM).
