Svaseq

WebAlthough svaseq isn’t directly supported in the facile workflow, we can still do this by first extracting the data we need into objects that svaseq can use, then marrying the surrogate variables that were estimated over our samples back with the FacileDataSet for use within the differential expression analysis workflow. WebApr 20, 2024 · 1 There are a number of methods. If you're doing DE, you have ComBatSeq, SVAseq, RUVseq, BUSseq. You could also try Z-score normalization ( ( x − x ¯) / σ) or even quantile transformation. For the latter two, make sure you work on each batch individually, not the whole dataset at once. See more on that here.
