Hi there,

I am using CHAMP to perform differential methylation analysis, including DMP and DMR. Regarding DMR, I used DMRcate algorithm and I am a little bit confused about the result.

In the derived table of DMRcate embedded in CHAMP, I got a column of overlapping.promoters. For example:

                        seqnames    start      end width strand no.cpgs        minfdr      Stouffer  maxbetafc meanbetafc

And what confusing me is why there is a number coming after each gene, like GATA5-001, what is that supposed to mean? And how can I select the significant DMR, just refer to mindfr or stouffer? What about the threshold? I didn't see the threshold in its R help document.

Hope someone could give me a hint! Many thanks advanced.
