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?
