# Repeat records of single trait model

Running repeat records model is nearly the same with fitting single trait model, the only difference is that repeat records model can fit the permanent environment effect, which can be achieved by assigning individual id at the first column of phenotype file to environmental random effect, take GBLUP model for an example:

./hiblup --single-trait
--pheno demo.repeat.phe
--pheno-pos 2
--rand 1
--bfile demo
--out demo
