A graphical comparison of two genome scanning strategies.

Abstract

<p>sliding windows (SW) vs., creeping windows (CW). With SW a chromosome is split into non (or partly) overlapping windows of 40 K and while passing over genomic gaps, it may not perfectly overlie a selective sweep. CW implements an elevated resolution moving windows in steps of only one SNP forward. The approach bridges small (<10 K) gaps while it stops at larger gaps and re-starts at the opposite side. CW always centers a window relative to a sweep position.</p
