I need to represent the overlap of differentially expressed genes across multiple comparisons.
Essentially, I have the log2foldchange of my 4 samples (Control, Treatment 1, 2, 3). Obviously my comparisons are Control vs Treatment 1 Control vs Treatment 2 Control vs Treatment 3 Control vs Treatment 4
Now I want to understand how those 3 comparisons overlap too each other. How many up-regulated genes are commonly up-regulated by every treatment? How many just in the 1st treatment? and so forth.
Now I can see that I can create a sort of monster of Venn diagram by have 8 different "clouds" to intersect (4 comparisons up-regulated and down-regulated).
Is there a better way to represent my data?
