Hi dear all, after downloaded the illumina 450K methylation chip data from TCGA, I have identified the DMCs with Fisher test for each probe, but I have no idea to identify the DMRs. For example I wanna find out the different methy- regions with 1Kb long. Any tool can do it directly? Could any one share some ideas with me? Thanks a lot

Take a look at TCGAbiolinks, which provides functionality for this.

Thanks for your help. I have finally solved this problem, but what I use is the other tool called ChAMP., it can accept the beta value matrix as input. AND for the TCGAbiolinks, I have noticed it have this function, but when I read its code in GitHub, it seems do the same works for DMRs just as for the DMCs. Maybe I have some misunderstand for that, but finally I choose the other tool, and solve my problem. Thanks again.
