WebThe DESeq function runs a couple of processing steps automatically to adjust for different library size and gene-wise variability, which you can read about in the DESeq2 vignette. The counts that we have obtained via sequencing are subject to random sources of variation. WebIf we use parameter fitType, we obtained a few genes less. The PCR data matches to local fitType better. More strikingly, when we run three treatments together versus split into pairs of groups in DESeq2. Together gave us much less genes, but pairs gave us more genes with significant differential expression. PCR data matches pairs results much ... how are traditional ira taxed
