# RNAseqDownstream2report



[TOC]

RNA-seq下游数据分析-ballgown到报告。 以Rscript为主，对接PGx RNA-seq choppy现有pipeline，到生成RNA-seq分析报告所需的rds和csv文件。

## 整体流程图

包括一下几个文件：

1. **RNAseq_1_ballgown.R**：从ballgown的文件夹到基因表达水平表格（每列为样本，每行为基因）

2. **RNAseq_2_PCA.R** ： 计算PCA。

3. **RNAseq_3_cor.R**：计算correlation，输出choppy report所需的scatterplot图的rds和csv文件。

4. **RNAseq_4_pwDEG.R**：根据分组信息，计算两两差异信息。

5. **RNAseq_5_pwGSEA.R：**根据基因表达水平基于GSEA进行通路分析。

6. **RNAseq_6_enrichFunc.R：**根据差异基因进行GO和KEGG通路分析。

# Quick start

1. 准备文件：

   1. ballgown 文件夹
   2. summary_group 样本group信息

2. 确认事项：

   1. 所在机器的R/bioconductot安装包已完成（请参考library节查看）

   2. 所在机器联网（RNAseq_6_enrichFunc.R需联网计算）

      PGx服务器每天需重新联网。

   3. 代码、rdata、rds数据均已在运行目录下。

### 输出结果

该代码将输出一系列输出文件：

1. PROJECT_CODE_GROUPversus_deg.csv(rds)

   根据分组情况进行两两比较，每次比较的结果输出1个PROJECT_CODE_GROUPversus_deg.csv，一个PROJECT_CODE_GROUPversus_deg.rds。因此根据比较次数，将输出比较次数*2个文件。

   choppy report所需的火山图的rds和csv文件，（其中绘图时仅需rds文件，csv文件就看看）。

   例如：

   rnaseq_AvsB_degs.csv

   rnaseq_AvsB_degs.rds

   文件内容为：每次比较的差异基因、比较的组别信息、log2FC、-log10 P value、是否为DEG。默认情况下只输出DEG，若计算时设置参数“-a TRUE”，则输出所有基因，sigene标记为nonDEG和DEG两类。

   > "gene","versus","logfc","log10p","sigene"
   > "ENSG00000004776","A vs B",-2.82273809523809,1.50125858539637,"DEG"

   > "ENSG00000011677","A vs B",-2.19445238095238,1.55184587515544,"DEG"

2. PROJECT_CODE_deg_acrossgroups.csv

   将1产生的所有差异基因（仅差异基因）集合到一起，用于差异基因清单表展示。

   > "gene","versus","pvalue","log2FC"
   > "ENSG00000004776","A vs B",0.03153,-2.823
   > "ENSG00000007171","A vs B",0.0236,3.068
   > "ENSG00000011347","A vs B",0.04849,-1.105

   > "ENSG00000012504","A vs B",0.04607,3.357

3. PROJECT_CODE_GROUPversus_deg_stats.csv(rds)

   差异基因统计，用于choppy报告系统中的barplot图。

   > "number","type","versus"
   > 65,"upregulated","A vs B"
   > 138,"downregulated","A vs B"

每列的含义：

A table with GSEA results. Each row corresponds to a tested pathway. The columns are the following: 

- versus - compared group
- pathway – name of the pathway as in 'names(pathway)'; 
-  pval – an enrichment p-value; 
-  padj – a BH-adjusted p-value; 
-  ES – enrichment score, same as in Broad GSEA implementation; 
-  NES – enrichment score normalized to mean enrichment of random samples of the same size; 
-  nMoreExtreme' – a number of times a random gene set had a more extreme enrichment score value; 
-  size – size of the pathway after removing genes not present in 'names(stats)'. 
-  leadingEdge – vector with indexes of leading edge genes that drive the enrichment, see <http://software.broadinstitute.org/gsea/doc/GSEAUserGuideTEXT.htm#_Running_a_Leading>.

## RNAseq_6_enrichfunc.R

### 功能简介

利用 clusterProfiler包对不同比较中的差异基因进行GO和KEGG通路分析。

输入：RNAseq_4_pwDEG.R输出的差异基因清单表（PROJECT_CODE_deg_acrossgroups.csv）。

*注意联网*

本功能较慢，每组的分析约需5分钟。



### 代码参数

```shell
Usage: Rscript RNAseq_6_enrichfunc.R [options]


Options:
	-o OUT_DIR, --out_dir=OUT_DIR
		The output directory [default ./]

	-i INPUT, --input=INPUT
		The input DEG list in csv format. The first column: gene; second column: group. Required! 

	-e TYPE_GENE_ID, --type_gene_id=TYPE_GENE_ID
		The type of gene symbol. Could be either of EnsemblGID/EntrezID/GeneSymbol [default: EnsemblGID]

	-f NUMBER, --pvalueCutoff=NUMBER
		Cutoff value of p value. [default: 0.05]

	-m PADJUSTMETHOD, --pAdjustMethod=PADJUSTMETHOD
		Method of adjust p value. One of "holm", "hochberg", "hommel", "bonferroni", "BH", "BY", "fdr", "none". [default: BH]

	-q NUMBER, --qvalueCutoff=NUMBER
		Cutoff value of q value. [default: 0.2]

	-p PROJECT_CODE, --project_code=PROJECT_CODE
		Project code, which is used as prefix of output file. [default: rnaseq]

	-h, --help
		Show this help message and exit
