I want to draw heatmap using differential expression genes.
First, I mapped using hisat2, and then counted genes using htseq. From this expression count matrix, I used DESeq2 to detect DEGs.
Now I have DEG list. I want to draw heatmap about these DEGs.
Which expression value do many people use to draw heatmap ? In my pipeline (hisat2 → htseq-count → DESeq2), which data can be used to draw genes expression heatmap ?
