Hi, I was wondering if I could ask for confirmation regarding my understanding of logFC values. So I know when you get a negative logFC value, the gene is underexpressed, and when you get a positive logFC value, the gene is overexpressed. But is there a cutoff value?
I read in an article that they used the cut off value of 1.5: that a gene has to be below -1.5 to be underexpressed, and above 1.5 to be overexpressed, and anything in between in not differentially expressed. However, how do you assume that value? And is there a way to derive the cut-off?
Thank you in advance :)
