Hi all! I analyzed my RNAseq data with DESeq2 and I obtained a nice unsupervised Heatmap with my top 20 or top 50 DEGs. Now I would create a Heatmap showing only a list of about 15 genes of interest. Is there a way to do it? Thank you, Danika

Hi Danika,

I also need to do the same with a list of DEGs. Are you using FPKM values to plot the heatmap?

Thanks, Hamid

You can do this easily with pheatmap package from CRAN (or ComplexHeatmap if you want something from Bioconductor).

pheatmap(your_deg_matrix)

Dave Tang made a good tutorial on this.
