use geno.genetic_variance.val instead of geno.genetic_variance because now it is the Variance struct.
in impute_genotypes(), make sure the data type (Float32 or Float64) of genotypes is unchanged after imputation. Otherwise the impute_genotypes() will only create Float64 genotype matrix, and this will cause an error for BLAS.axpy!(oldAlpha-α[j],x,yCorr) when x is Float64 but yCorr is Float32.
fixed two bugs for single-step:
