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. WebVice versa, careless correction of batch effects can result in loss of biological signal contained in the data [6–8].
