-    =<pop>= gives the population in which the advantageous allele is born. =<Tend>= gives the generation at which sweep

-    allele in the middle of the region). The acceptable frequency range of the advantageous allele at time =<0>= (present-day) in selBegPop is specified as a range of numbers between 0.0 and 1.0, e.g. 0.5-0.95.  =<selBegPop>= specifies the population in which the
