使用selscan计算xp-ehh得到数据之后，之后进行selscan-2.0.0/bin/linux/norm --xpehh --files xx.xpehh.out --bp-win --winsize 20000
20kb窗口的归一化之后得到 Chr01.xpehh.out.norm.20kb.windows文件，已知 Chr01.xpehh.out.norm.20kb.windows 文件列名分别为<win start> <win end> <scores in win> <gt the fraction of XP-EHH scores >2> <lt the fraction of XP-EHH scores < -2> <approx percentile for gt threshold wins> <approx percentile for lt threshold wins> <max score> <min score>
想要根据某一篇文献的“The windows with the highest 1% of XP-CLR scores were considered as candidate
selective regions. XP-EHH and iHSwere implemented using the program
Selscan (v1.1.0). Results were normalized with a 20 kb window. The ratio of
extreme scores (|score| > = 2) in each window were calculated. The top 1% of
windows (with the highest ratio of extreme scores) were considered to be candidate
selective regions.” 进行筛选top1%窗口，Chr01.xpehh.out.norm.20kb.windows 应该要筛选哪一列取top呢？

我理解的是|score| > = 2应该是要提取的是<gt the fraction of XP-EHH scores >2> 和<lt the fraction of XP-EHH scores < -2> 这两列的top，你觉对吗
