相信不少小伙伴在Top文章经常看到过这样美美的圈图，即我们常说的circos图，那么今天就来简单介绍一下该软件的安装和操作。
打开circos官网地址(http://circos.ca/)，我们看到的就是circos网站的首页图，点击最上边的GET STARTED。
打开界面如下：
上面可以直接点linux版本或者windows版本进行下载安装，具体的安装步骤可以参考官网(http://circos.ca/tutorials/lessons/configuration/unix_vs_windows/)，安装好后根据不同的版本进行操作即可。
On UNIX (e.g. Linux),在虚拟机或者liunux服务器上安装步骤如下
# UNIX> cd example
> ./run# batch file runs 'circos -conf etc/circos.conf'debuggroup summary 0.86s parsing karyotype and organizing ideograms
debuggroup summary 1.08s applying global and local scaling
debuggroup summary 1.15s allocating image, colors and brushes
debuggroup summary 7.19s drawing highlights and ideograms
debuggroup summary 8.94s processing links
debuggroup summary 13.31s processing data tracks
Processing text track - this might take a while
debuggroup summary 68.75s generating output
created image at ./circos.png
created image at ./circos.svg# look at circos.png
On Windows,安装步骤如下
# Windows> cd example
> perl ..\bin\circos -conf etc\circos.conf
You can always leave out the -conf etc\circos because Circos will find it automatically.
> perl ..\bin\circos
If you get a "configuration file not found" error, then you are very likely not in the example directory. To check, use cd which will report the current directory. It should be where you installed circos.
> cd
C:\circos\example
利用circos软件的示例文件运行代码绘制circos图非常炫酷，有png和svg两种格式，大家可以试一试。
circos图今天就先给大家介绍到这里，希望大家的科研能有所帮助！祝您科研顺利快乐！
