A Heatmap based on RPKM values of log2fold change?

Question

[Mehmet]

Dear All;

I would like to ask you a question. ( I searched on the internet and here, but I could not find a good explanation).

I have a list of differentially expressed genes, and their GFOLD values with RPKM values. Briefly, I have two species and I run GFOLD for differential gene expressed analysis. GFOLD produced a table containing up and down regulated genes with their RPKM values. Then, I selected up and down regulated genes based GFOLD values. Now I want to make a heatmap. Can RPKM values of each up and down regulated genes be used in heatmap in R after making a matrix using RPKM values?

Thank you.
