The phe file


Quantitative trait values are written in the phe file. The file has 3 columns if one trait is simulated and has 4 columns if two traits are simulated. The first two columns are the family ID and individual ID. The IDs correspond to the IDs in the ped file. The third column specifies the trait values for the first trait. The fourth column specifies the trait values for the second trait.
