Below is a list of all possible parameter file xml elements. For each element an example is provided as well as information about the element's host element, the element's type and the element's content. '''Note that all words(element names, key string words, key string variables) in bold are hard-coded, all in italic are user-defined (this does not apply to the example box)'''. The spelling of hard-coded words must be abide by, the spelling of user-defined words is user-defined.

Below is a list of all possible parameter file xml elements. For each element an example is provided as well as information about the element's host element, the element's type and the element's content. Note that all words(element names, key string words, key string variables) in bold are hard-coded, all in italic are user-defined (this does not apply to the example box). The spelling of hard-coded words must be abide by, the spelling of user-defined words is user-defined.

 gamma compulsory hosts information about $$\Gamma$$ being constructed as combined single step relationship matrix H using pedigree pedigree name and genomic information. the genomic information can be supplied
  • via a grm element for single step H-BLUP models
  • via a genotype element for single step T-BLUP models

Note that for type:tblup it is not necessary to have an automatic-optional <grms> element in the parameter file. Doing so will cause the construction and RAM-storage of $$G$$ although it is not need for building H, thus maybe leading to substantial increase in processing time and RAM demand.

  • if aweight>0.0, nothing will be added to the diagonals
