 IM is a program for the fitting of an isolation model with migration to haplotype data drawn from two closely related species or populations. Large numbers of loci can be studied simultaneously, and different mutation models can be used. IM estimates the divergence time and the migrations having occurred in the ancestry of two populations, which might have grown exponentially since split. Important limitations of the basic model are that it cannot account for changes in population sizes, and it cannot account for the sizes of founding populations\\ IM is a program for the fitting of an isolation model with migration to haplotype data drawn from two closely related species or populations.

 IMa also allows log likelihood ratio tests of nested demographic models. IMa is faster and better than IM (i.e. by virtue of providing access to the joint posterior density function), and it can be used for most (but not all) of the situations and options that IM can be used for IMa also allows log likelihood ratio tests of nested demographic models.
