Scan across chromosome 17 for the joint CEU + YRI populations. We conduct an extensive local search for a known inversion on chromosome 17. We show the BIC values for each sliding window of size 0.4 Mb; a horizontal line indicates the zero level for which the inversion model favors the mixture of inverted and non-inverted populations. The inversion at 17q21 (~ 40 Mb) is clearly visible. The full list of inversions are given in Additional file 1, Table S4.
