Executablesheadline bar To make the programs accessible to as many users as possible, windows executables are available for download. These executables were created using the G95 compiler. This compiler seems to work well with the MTDFREML code, although several compiling errors were recently fixed (Sept. 2021), so if you have an older version of the Fortran code, it would be wise to grab a current version of the program HERE. The G95 compiler is available on a number of platforms and can be obtained athttps://www.g95.org/downloads.shtml. Several different versions of PARAM.DAT were used to compile MTDFPREP and MTDFRUN. The Zip files containing all 3 executables (MTDFNRM, MTDFPREP, and MTDFRUN) as well as the contents of the PARAM.DAT are provided for each set of executables. For all versions of the executables, MTDFNRM was compiled with a maximum number of 100,000 animals in the pedigree.  Set
