Description

This project provides fortran scripts to apply, with ASReml, structured antedependence models (SAD) for single trait analysis, multiple-trait analysis or single trait analysis with correlated random effects.

It contains:

- 3 fortran programs: 1) sadmultiuni.f90 to run SAD models with versions 1 to 3 of ASReml 2) sadmultiuni4.f90 to run SAD models in ASReml4 3) matrixSAD.f90 to calculate variance-covariance matrix using SAD parameters.

- 1 tutorial (sadmultiuni_tutorial.pdf)

- 2 sets of examples (ex1.as, ex2.as and their data, pedigree and parameters files)
