Dear RNA-seq experts,

I have a problem with RNA seq analysis,

After DEG analysis using edgeR,

genes that have large variation between samples are not defiend as DEGs.

In my concepts, it's weird because their expression levels are very vary (like FPKM: 0, 3) in pairwise comparison. And in the graph attached, the dots on bottom of x axis and y axis are gray (RED: DEGs, both FPKM
