Comparison of Bisulfite sequencing results with Methylkit and edgeR

Question

[iraia.munoa]

Hi everybody, I have been trying different tools to analyse the differentially methyted cytosines in bisulfite sequencing samples (control vs treatment). I have used on one hand Methylkit tool and have obtained %of differentially methilated cytosines. On the other hand, I have used edgeR and have obtained fold change values for differentially methylated cytosines. Now I wold like to compare both results and see which cytosines have been identified with both tools, comparing if their values are similar. How can I compare %methylation values (methylkit) and fold change values (edgeR), without adding any type of error? Thanks in advance, Iraia
