Recently I used TCGA database Methy450 to select differential methylation sites between cancers.

I got results like this；

cgIDs   Fold_Change     Genome_Build    CHR     MAPINFO UCSC_CpG_Islands_Name

cg00890041      20.186885601531078      37.0    6       31830570.0      chr6:31830299-31830948

For each CpG Sites, HumanMethylation chip supplies MAPINFO and USCS_Islands_Name information etc. . I am wondering the methylation expression values is corresponding to location of MAPINFO or region of UCSC_CpG_Islands_Name?

Thanks!
