These tracks show probability of introgression obtained by ARGweaver using a population-based model. Methods are described in Hubisz,Williams,Siepel(2019). These tracks show results presented in the supplement, in which we used a migration time of 150kya and a super-archaic divergence time of 1.5Mya.
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 population of introgression indicated by the colors. (Neanderthal=red, Denisovan=blue, Human=green, Super-Archaic hominin=gray). 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.
