wget 下载 refGene

http://genome.ucsc.edu/cgi-bin/hgTables

 wget -c -O mm9.refGene.txt.gz http://hgdownload.soe.ucsc.edu/goldenPath/mm9/database/refGene.txt.gz
 wget -c -O mm10.refGene.txt.gz http://hgdownload.soe.ucsc.edu/goldenPath/mm10/database/refGene.txt.gz
 wget -c -O hg19.refGene.txt.gz http://hgdownload.soe.ucsc.edu/goldenPath/hg19/database/refGene.txt.gz
 wget -c -O hg38.refGene.txt.gz http://hgdownload.soe.ucsc.edu/goldenPath/hg38/database/refGene.txt.gz

以hg38为例，进入terminal，选定文件夹后，运行

$ wget -c -O hg38.refGene.txt.gz http://hgdownload.soe.ucsc.edu/goldenPath/hg38/database/refGene.txt.gz

得到hg38.refGene.txt.gz
解压缩，

$ gunzip hg38.refGene.txt.gz

查看里面的内容，

$ less -S hg38.refGene.txt

提取其中的带有geneID的一列，并且没有重复

#示例而已
$ awk '{print $7}' refGene.list.txt | sort -u > uniqu.refGene.list.txt

查看列数

 $ wc -l uniqu.refGene.list.txt 
28006 uniqu.refGene.list.txt
