1、下载坐标转换对应文件，hg38到hg19
#hg19到hg38网址：http://hgdownload.soe.ucsc.edu/goldenPath/hg19/liftOver/hg19ToHg38.over.chain.gz
wget http://hgdownload.soe.ucsc.edu/goldenPath/hg38/liftOver/hg38ToHg19.over.chain.gz
gunzip hg38ToHg19.over.chain.gz
2、下载转换工具
wget -c http://hgdownload.cse.ucsc.edu/admin/exe/linux.x86_64/liftOver
chmod 755 liftOver
#查看帮助
./liftOver
3、测试
#格式：liftOver oldFile map.chain newFile unMapped
bash liftOver CTCF_CT_peaks.bed hg38ToHg19.over.chain CTCF_CT_peaks_hg19.bed unMapped
