These tracks show probability of introgression obtained by ARGweaver using a population-based model. Methods are described in Hubisz,Williams,Siepel(2019). This set of tracks shows the results in which we looked for Neanderthal and Denisoivan introgression into modern humans. The samples included SGDP humans Basque_2F, Mandenka_2F, and Khomani_San_1F. The ARGweaver model had a migration band from both Neanderthal and Denisova into modern humans at 50kya.
The "Regions" track shows the predicted introgressed regions using a posterior probability cutoff of 0.5. There is one sub-track per individual, with the source of introgression indicated by the colors. (Neanderthal=red and Denisovan=blue. Darker shades are used to indicate homozygous introgressed regions. The remaining tracks show the posterior probability of each type of introgression event in each individual, averaging across MCMC iterations.
