... Jeff, I followed your suggestion. I created a simulated RNA-Seq dataset (15000 genes and 30 samples for each of the 2 conditions) with 3 batch effects (strong, medium and weak effects). Then, after VST normalization, I calculated: uu_val, as discussed above; uu_val2 <-uu$values^2 / sum(uu$va ...

Let's say I found my ten SV with sva function; my question is: how can I calculate the  proportion of variance explained for each SV, as for PCs in PCA? Thanks a lot, Mattia ...
