... Hi, Without replicates, you cannot hope to test meaningfully for statistically significant differences, with DiffBind or anything else. The DiffBind vignette describes two approaches to analysis.  You might look into an "occupancy" analysis, which allows you to, for example, draw Venn diagrams sho ...
