This file describes how I installed Tine et al.'s modified version of ∂a∂i software on the BYU FSL supercomputing cluster marylou, and got it working, on April 15, 2017. Tine et al.'s modification of ∂a∂i permits models of heterogeneous migration between lineages, consistent with introgression of specific regions of the genome.
Tine et al.'s modification of ∂a∂i v1.6.3 is distributed in a "dadi-1.6.3_modif" folder containing the distro, which is available as part of a blog post at this SEA Lab website. Go to the bottom of the blog post and then download the modified ∂a∂i archive from this link.
