GEBVtest Merged Files

The gebvtest.py program offers an option (-m, --mergefiles) to create a file of merged Cf/Df/Cr/Gr records as a convenience to the user. These files can make it easier to check for the correctness of the input datasets and they can be used perform additional checks and/or statistical analyses, using R for example as in this small test.R.

One file is created for each trait present in the traits_POPBRD file and the file300Xy_POPBRD files. There is a record for each bull present in the Cf file born in/after the cutoff year specified in the traits_POPBRD file. Flags are supplied to indicate whether the bull qualifies as a candidate or a test bull. Please see the file format below.

By default, the files are created in directory DATADIR/merged. The merged files do not have a _POPBRD extension, so if you would like to create files for more than one population or breed, you should also supply the -M, --mergedir option with a different destination directory for each population/breed. The destination directory can be an absolute path, or it can be relative to the programs directory (eg. ../sample_data/my_merges). The directory will be created automatically if it does not exist.

File format

The file is in comma-separated-variable (csv) format, using commas as the separator.
