5.4.4 genedrop computational parameters

set marker seeds H1 H2

This statement initializes the seeds for the random number generator in the gene dropping algorithms. The seeds are to be positive and no greater than hexadecimal 0xFFFFFFFF, with the first seed (congruential seed) odd, and the second seed (Tausworthe seed) nonzero. In genedrop, markers are simulated before traits, so that, if no seeds are specified for marker simulation, default seeds (0x3039 0x431) are used.

set trait seeds H1 H2

This statement initializes the seeds for trait simulation. If no seeds are given, the starting seeds for trait simulation are the seeds returned by the random number generator at completion of marker simulation. Note that if output of marker seed is requested, this will be the same value as is output to the marker seed file for a subsequent genedrop run.
