Results of EDAR in the visualization interface. Data are illustrated in three parts as Overview (chromosome scale), Region (area
of searching target and flanking sequences), and Details (searching target). The Overview
shows the FST values of 100 kb sliding windows (maroon) and the low HET regions of merged window
outliers in HapMap geographical group of ASN (red), CEU (green), and YRI (blue) along
the ideogram of the chromosome. Region image displays the normalized HET values of
100 kb sliding windows that flanking the searching target in each population with
the same color as illustrated in Overview. The basic line (zero) represents the average
values of Normalized HET, therefore the comparatively high HET windows are shown above
zero and low HET windows appear below the basic line. For the Details of the searching
target, it provides (from the top to the bottom) the fine position in the chromosome,
the low HET region (merged outliers of sliding windows) in the geographical group
(red bar for ASN in EDAR gene), the genes (incarnadine) with the arrow pointing to
the transcription direction, the transcripts and the frame usage of the genes (grey),
the SNP outliers of iHS in each population as colored sticks, and at last the SNP
outliers of FST (maroon) to demonstrate if differentiation signals exist among three populations.
For EDAR gene with a yellow label as the target gene, it is localized in a highly
differentiated region among the geographical group and much more iHS outliers are
in ASN than that in CEU and YRI groups. In addition, FST outliers are also enriched in EDAR.
