WebOct 14, 2024 · As ChIP-seq datasets increase in public repositories, it is now possible and necessary to account for complex sources of variability in ChIP-seq data analysis. We find that two types of variability, the batch effects by sequencing laboratories and differences between biological replicates, not associated with changes in condition or state, vary ... Web1. So what's happened here is that your samples are very similar to each other, and the other conditions are very different from each other. The middle of your samples and the average of all other conditions is now coincident: they both are centered on (0,0). I'm not sure this is going to work as a method of comparison.
