 ### 甲基化原理简述
 
+![](.\picture\BS原理.png)
+
 全基因组亚硫酸氢盐测序用于研究基因粒度的DNA甲基化模式。 亚硫酸氢盐处理将胞嘧啶转化为尿嘧啶，但甲基化胞嘧啶不变。
 
 比对软件（如Bismark）将基因组序列转化之后进行比对。

 ### APP功能简述
 
 为了更好的分析全基因组甲基化数据，我们选用了目前最好的比对软件Bismark，构建了分析pipeline。用来提取全基因组的CpG，CHH,CHG甲基化模式信息。
 
 ### WGBS分析流程

 ## 输入和输出
 以CpG_context_test_data_bismark_bt2.txt为例
 
 ```

 第一行为Bismark的版本信息
 不同字母表明不同的甲基化状态：
 
 ```
-
 X 代表CHG中甲基化的C
 x  代笔CHG中非甲基化的C
 H 代表CHH中甲基化的C
 z  代表CpG中非甲基化的C
 U 代表其他情况的甲基化C(CN或者CHN)
 u  代表其他情况的非甲基化C (CN或者CHN)
-
 ```
 
 #### 补充文件
 
 上面的文件是methylation calling 最直接的证据，但是对于甲基化水平的定量来说，缺少了相关信息。运行bismark_methylation_extractor时，除了生成上述文件之外，还会有下列3个文件：
 
-```
-
 test_data_bismark_bt2_splitting_report.txt
 test_data_bismark_bt2.M-bias.txt
 test_data_bismark_bt2.M-bias_R1.png
 
-
-
-```
-
-
-
 ##### test_data_bismark_bt2_splitting_report.txt
 
 记录了该样本甲基化的汇总信息
 
 ```
-
 Final Cytosine Methylation Report
 Total number of C’s analysed:    40348
 Total methylated C’s in CpG context:    1365
 C methylated in CpG context:    66.8%
 C methylated in CHG context:    0.2%

 ```
 
 ##### test_data_bismark_bt2.M-bias.txt
 部分文件内容如下
 
 ```
-
