GO/Pathway 数据筛选
GO功能分析
一、显著性筛选
显著性P值
采用Fisher精确检验，对功能分析结果的显著性判断，一般选择P<0.05的功能为具有显著统计学意义的功能。
显著性FDR值
为了控制多重比较检验中犯第一类错误的整体概率，我们通过Benjamini-Hochberg step-up的方法来控制FDR，即判断为显著性的GO中假阳性GO的比例的期望，一般选择FDR<0.05是较为理想的结果，表示对应的功能具有显著统计学意义。

根据用户关注的基因或功能名称中包含的关键字进行筛选，可同时输入多个基因/关键字。
信号通路（Pathway）分析
一、显著性筛选
显著性P值
采用Fisher精确检验，对通路分析结果的显著性判断，一般选择P<0.05的通路为具有显著统计学意义。
显著性FDR值
为了控制多重比较检验中犯第一类错误的整体概率，我们通过Benjamini-Hochberg step-up的方法来控制FDR，即判断为显著性的Pathway中假阳性Pathway的比例的期望，一般选择FDR<0.05是较为理想的结果，表示对应的通路具有显著统计学意义。
