population model parameters
set [chromosome I] markers K1... frequencies X1 X2...
This statement specifies markers allele frequencies. More than one marker (on the same chromosome) can be specified in one statement if they have the same number of alleles and the same allele frequencies.
set traits K1... frequencies X1 X2
This statement specifies the trait allele frequencies. More than one trait can be specified if they have the same allele frequencies. Note that the traits have to be biallelic.
set normalized frequencies
If the set of allele frequencies for each marker and trait is to be normalized, this statement is given. Normalization of the frequencies is recommended when simulating pedigree data, but not recommended when using the other programs.
set traits K1 ... genotype means X1 X2 X3
Since two alleles are simulated for each trait, three means are specified for the polygenic trait values: one each for the (1 1), the (1 2) or (2 1), and the (2 2) genotypes. The default values for traits with no means specified are 0.0, 0.0, 0.0.
set traits K1 ... additive variance X
set traits K1 ... residual variance X
This statement is like the preceding one. An environmental component is assigned to the polygenic trait.
