使用xps和oligo分析Affymetrix Exon/Gene ST Arrays 26

首先安装xps和oligo。

安装oligo比较简单。直接

 source("http://www.bioconductor.org/biocLite.R")
 biocLite("oligo")

就可以了。

而安装xps可能麻烦一点，首先要安装ROOT，其主页为http://root.cern.ch/drupal/

而后是安装xps，为了确保安装效果，请使用：

 source("http://www.bioconductor.org/biocLite.R")
 biocLite("xps",type="source")

安装成功之后，就可以使用library(xps)调用了。

好了，我们先使用oligo来分析。

至此，我们手头就有了基因水平的表达结果，其后就可以使用limma来获得差异表达的基因了。

我们使用xps来分析。

博主，您好，看了您的文章，想请教您，“而安装xps可能麻烦一点，首先要安装ROOT，其主页为http://root.cern.ch/drupal/”我下载了”root_v5.34.14.source.tar”,这个解压了就相当于安装了,是吗？还有这个要安装在哪里？是和R一个文件夹里吗？还有“糗世界”在哪里注册啊？
- Reply admin 1月 21,2014 9:30 上午
  
  对，直接安装就好了。不需要在一个文件夹中，但是需要让系统能找到你安装的目录，具体在windows下我无法测试。糗世界无法注册。

至此，我们手头就有了基因水平的表达结果，其后就可以使用limma来获得差异表达的基因了。

博主，有没有博文讲下一步limma的分析啊

All the CEL files must be of the same type.

怎么办啊
- Reply admin 11月 12,2014 2:00 下午
  
  检查你的CEL文件是不是都是相同的affymetrix公司的平台的数据。你可以直接使用文本文档打开CEL文件，查看最初几行，看看它们的型号是否一致。如果是来自于不同型号的芯片，分开分析。

  root的安装比较复杂。我建议您参照root的安装说明一步一步来。有些时候，可以试着使用port, fink等工具。

  看情况，你还是使用oligo更合适一些。安装ROOT对于你可能有些过于困难了。
