I have a candidate set of genes whose expression I would like to visualize in heatmap format.
As I have several transcriptome/proteome studies, I cannot represent them all as a single heatmap, as log2FC is relative.
Is there any global variable I can calculate to compare/visualize the fold changes of these genes? My goal is to look at a particular gene across several studies and see if its expression is consistent.
All the studies, although from different independent experiments are from the same tissue samples.
