Changing a univariate script to a multivariate script
Uni-, bi- and multivariate versions are given for most scripts, but you can easily change this yourself. Most scripts have a ?#define nvar 1? in the first lines. Changing the 1 into a 2 will change the script from uni-variate to bivariate. Note also that the nvar refers to the number of phenotypes to be per individual.
All scripts are set up so that the matrix dimensions will change accordingly. However, you may need to add starting values for new matrix elements. And you may also want to test additionally models in an option multiple (e.g. drop X 1 2 4, for dropping a genetic covariance between the second and the fourth variable).
