Since your responses helped me many times before, I'm posting two more
questions about Lumi:
* Can I filter genes that are below a certain detection pvalue out of my
file to speed up following analyses? How can I do that, at what stage and
what should be the threshold?
* I'm suspecting a batch effect in my data. I can work with ComBat, but I've
no idea how to get the adjusted values back into Lumi (a lumibatch) to go on
with transformation and normalization procedures. Any ideas?
