没想到碰到了一个神器:PROGENy。可以给常见的14种signaling pathway活性打分。

历史分析:
- pathway是一个不得不研究的主体,比如我们的paper就给很多GO pathway的基因打分了,很简单就是一个求均值。
- 关于complex的活性打分,就得使用几何平均,因为缺失任何一个都会导致complex失活。
现有工具:
- AUCell allows to identify cells with active gene sets (e.g. signatures, gene modules...) in single-cell RNA-seq data. AUCell uses the "Area Under the Curve" (AUC) to calculate whether a critical subset of the input gene set is enriched within the expressed genes for each cell.
- 为基因集进行打分常见的富集分析软件GSVA
- Calculate module scores for feature expression programs in single cells:AddModuleScore
目前任务:给Wnt和RA通路打分
初步设想:分component activity和target gene activity两个维度来衡量。
