Hi there, I'm writing to the list to have your comment about the
possibility of using edgeR or DESeq for the analysis of ChIP-seq
samples.
Standard approaches to ChIP-seq analysis (relying on external software
such as MACS) do not make analysis of replicates easy. I've seen
people looking for peaks and then compare the common/differential
intervals between replicates in case/control design. I wonder if a
more general approach may work (and I'm going to test this anyway...).
Since the negative binomial model stands for ChIP-seq analysis, both
edgeR and DESeq should work well. One can use external software to
identify regions and compute the union of all regions as it was a
"gene list". From that point on, the pipeline should not differ from
standard gene expression analysis.
What do you think?
