Q: 老师您好,请问差异分析为什么使用 RNA assay ?而不是用 SCT assay 或者 Integratedassay? RNA assay 不是未经过标准化和批次校正的原始数据么?/ 整合数据后进行 findmarker分析时是采用 integrated assay 还是 RNA assay?
A: 这个问题也困扰了我很久,后来我在 GitHub 上找到了官方的解释: As a general rule, wealways recommend performing DE on originally measured values - instead of on batchcorrected, imputed, etc. values. This ensures that the measurements that enter the DE test are indeed independent from each other, which is a requirement of any statistical DE test.
