WebDec 1, 2011 · Motivation: Structural variation (SV), such as deletion, is an important type of genetic variation and may be associated with diseases. While there are many existing methods for detecting SVs, finding deletions is still challenging with low-coverage short sequence reads. Websva is mostly useful for estimating batch effects when you don't know what the batches/artifacts are. if you know the batch effects, you can build a model matrix including them as terms in the matrix and then use limma/voom, DESeq, edgeR, etc. fallin medical practice

I understand GSEA/GSVA can take microarray-like expression matrix such as the output of voom () or vst (). However, I have a question on how we can also use svaseq () variables, correct the output from voom () or vst (), and apply GSVA on it. I assume this is possible since I have read papers showing PCA after correction by SVA …

You could also try Z-score normalization ( ( x − x ¯) / σ) or even quantile transformation. For the latter two, make sure you work on each batch individually, not the whole dataset at once.
