I got a list of genes (<1000) for which I want to perform DEG-Analysis. Since I'm only interested in certain genes, I want to filter out the rest to reduce false-negative results and get more information about the genes I'm actually interested in.
Is there a simple way to do this with limma, or can I somehow filter genes from a expression set? If I try to fit a exprs-Matrix instead of a exprs-Set, I'm excluding genenames, GO annotations, etc. which is very unpleasant.
Thanks in advance!
