				<content:encoded><![CDATA[<p style="text-align: center;"><b>转录组</b><b>cummeRbund操作笔记</b></p>
<p>这是跟tophat和cufflinks套装紧密搭配使用的一个R包，能出大部分文章要求的标准化图片。</p>
<p>一：安装并加装该R包</p>
<p>安装就用source("http://bioconductor.org/biocLite.R") ;biocLite("cummeRbund")即可，如果安装失败，就需要自己下载源码包，然后安装R模块。</p>
<p><a href="http://www.bio-info-trainee.com/wp-content/uploads/2015/03/转录组cummeRbund操作笔记220.png"><img class="alignnone size-full wp-image-272" src="http://www.bio-info-trainee.com/wp-content/uploads/2015/03/转录组cummeRbund操作笔记220.png" alt="转录组cummeRbund操作笔记220" width="554" height="199" /></a></p>
<p>然后把cuffdiff输出的文件目录拷贝到R的工作目录，或者自己设置工作目录</p>
<p>&nbsp;</p>
<p>二：读取FN目录下面的所有文件。</p>
<p><a href="http://www.bio-info-trainee.com/wp-content/uploads/2015/03/转录组cummeRbund操作笔记239.png"><img class="alignnone size-full wp-image-273" src="http://www.bio-info-trainee.com/wp-content/uploads/2015/03/转录组cummeRbund操作笔记239.png" alt="转录组cummeRbund操作笔记239" width="466" height="181" /></a></p>
<p>可以看到把cuffdiff下面的文件夹所有的文件都读取到了，里面有如下文件，包括genes，isoforms，cds，tss这四种差异情况都读取了。</p>
<p><a href="http://www.bio-info-trainee.com/wp-content/uploads/2015/03/转录组cummeRbund操作笔记316.png"><img class="alignnone size-full wp-image-274" src="http://www.bio-info-trainee.com/wp-content/uploads/2015/03/转录组cummeRbund操作笔记316.png" alt="转录组cummeRbund操作笔记316" width="518" height="254" /></a></p>
<p>&nbsp;</p>
<p>三：表达水平分布图</p>
<p><a href="http://www.bio-info-trainee.com/wp-content/uploads/2015/03/转录组cummeRbund操作笔记328.png"><img class="alignnone size-full wp-image-275" src="http://www.bio-info-trainee.com/wp-content/uploads/2015/03/转录组cummeRbund操作笔记328.png" alt="转录组cummeRbund操作笔记328" width="526" height="63" /></a></p>
<p><a href="http://www.bio-info-trainee.com/wp-content/uploads/2015/03/转录组cummeRbund操作笔记330.png"><img class="alignnone size-full wp-image-276" src="http://www.bio-info-trainee.com/wp-content/uploads/2015/03/转录组cummeRbund操作笔记330.png" alt="转录组cummeRbund操作笔记330" width="553" height="419" /></a><br />
四、表达水平箱线图</p>
<p>csBoxplot(genes(cuff_data))</p>
<p><a href="http://www.bio-info-trainee.com/wp-content/uploads/2015/03/转录组cummeRbund操作笔记371.png"><img class="alignnone size-full wp-image-277" src="http://www.bio-info-trainee.com/wp-content/uploads/2015/03/转录组cummeRbund操作笔记371.png" alt="转录组cummeRbund操作笔记371" width="554" height="422" /></a><br />
五、画基因表达差异热图</p>
<p><a href="http://www.bio-info-trainee.com/wp-content/uploads/2015/03/转录组cummeRbund操作笔记386.png"><img class="alignnone size-full wp-image-278" src="http://www.bio-info-trainee.com/wp-content/uploads/2015/03/转录组cummeRbund操作笔记386.png" alt="转录组cummeRbund操作笔记386" width="511" height="617" /></a></p>
<p>画出热图如下</p>
<p><a href="http://www.bio-info-trainee.com/wp-content/uploads/2015/03/转录组cummeRbund操作笔记396.png"><img class="alignnone size-full wp-image-279" src="http://www.bio-info-trainee.com/wp-content/uploads/2015/03/转录组cummeRbund操作笔记396.png" alt="转录组cummeRbund操作笔记396" width="475" height="347" /></a></p>
<p>&nbsp;</p>
<p>六、得到差异的genes,isoforms,TSS,CDS等等</p>
<p>&nbsp;</p>
<ul>
<li>得到上调下调基因列表</li>
</ul>
<p>diffData &lt;- diffData(myGenes )</p>
<p><a href="http://www.bio-info-trainee.com/wp-content/uploads/2015/03/转录组cummeRbund操作笔记430.png"><img class="alignnone size-full wp-image-280" src="http://www.bio-info-trainee.com/wp-content/uploads/2015/03/转录组cummeRbund操作笔记430.png" alt="转录组cummeRbund操作笔记430" width="554" height="171" /></a></p>
<p><a href="http://www.bio-info-trainee.com/wp-content/uploads/2015/03/转录组cummeRbund操作笔记474.png"><img class="alignnone size-full wp-image-281" src="http://www.bio-info-trainee.com/wp-content/uploads/2015/03/转录组cummeRbund操作笔记474.png" alt="转录组cummeRbund操作笔记474" width="554" height="134" /></a></p>
<p>&nbsp;</p>
<p>只有一百个有表达差异的基因</p>
<p><a href="http://www.bio-info-trainee.com/wp-content/uploads/2015/03/转录组cummeRbund操作笔记490.png"><img class="alignnone size-full wp-image-282" src="http://www.bio-info-trainee.com/wp-content/uploads/2015/03/转录组cummeRbund操作笔记490.png" alt="转录组cummeRbund操作笔记490" width="212" height="121" /></a></p>
<p>&nbsp;</p>
<p>&nbsp;</p>
<p>最后贴出一个综合性的代码，算了，太浪费空间了，把整个空间搞得不好看，就不贴了。</p>
<p>这个代码可以自动运行出图;</p>
<p><a href="http://www.bio-info-trainee.com/wp-content/uploads/2015/03/转录组cummeRbund操作笔记3781.png"><img class="alignnone size-full wp-image-283" src="http://www.bio-info-trainee.com/wp-content/uploads/2015/03/转录组cummeRbund操作笔记3781.png" alt="转录组cummeRbund操作笔记3781" width="554" height="384" /></a></p>
