1.最常用的在线网站David：

然后用R进行可视化

good：可以自行筛选GO/KEGG进行可视化

The Fold Enrichment is defined as the ratio of the two proportions. For example, if 40/400 (i.e. 10%) of your input genes involved in "kinase activity" and the background information is 300/30000 genes (i.e.  1%) associating with "kinase activity", roughly 10% / 1% = 10 fold enrichment

2.R包：clusterprofile

good：一套全，出图相对漂亮点
