"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 ... " - Deseq dds fittype mean
