Dear Bioconductor users,

Before I performed Limma analysis, should I do non specific filter or not?
If we should do filter before Limma step, how do I determine the cut-off for
filtering-function? For example, If I use Co-efficient of  Variability (CV)
as filtering criteria, how should I set the cut-off? arbitrarily?

Thanks in advance.
