I am analysing the SNP-based heritability of production trait (e.g. milk) and want to add herd effect into the model as random effect. For fixed effect I can prepare the file (e.g. test.covar) and use it with --covar flag. How I can prepare the random file and what flag I should use in the command line? The example of my command is below: gcta64 --grm testgrm --autosome-num 29 --autosome --pheno test.phe --reml --covar test.covar --out vartest
Best Regard,

I think you can add enviornmental random effects (above the genetic component) by specifying a covariance matrix for another variance component. Maybe this reference is useful: doi.org/10.1016/j.ebiom.2016.11.003
