WebThe default in edgeR is to adjust the p-value in order to control the false discovery rate (FDR). If you control the FDR at a given level for each of 5 contrasts separately, then you have automatically controlled the FDR at the same level for all 5 contrasts together. The FDR is a scalable quantity in this sense. WebedgeR.
