IMIG aims at estimating pairwise rates of migration between discrete populations using multilocus genotypes. The inference is based upon changes in the genetic composition of populations during the dispersal phase of a species' life cycle. IMIG requires populations to be sampled twice: the first sample, "sample 1", is the pre-dispersal data, and some time later the second sample, "sample 2", is the post-dispersal data. IMIG will estimate the pairwise rates of dispersal that occurred in the time between these two samples.
