Lets say you have three transcriptomes taken from the same plant in three different conditions. You then got a list of differentially expressed genes for each of these conditions. You want to compare these lists to see how many genes are unique to one condition and how many genes are differentially expressed between condition AB, condition AC, BC and ABC. Something like figure 2 from this paper.
Is there a good program or way to do this? I've been googling excel tutorials for a while, and my experience with programming is minimal. Any advice? Thank you!
