Dear all, I have a list of CpG island methylation array IDs, like "CHR0100P000018599", I would like to convert these IDs into target IDs as "cg....." or probID. Is there some quick r package I could apply for directly? or do I need mapping with the chr number and position? Thanks in advance! Best, Xinhui
From which array is it ? You may be able to retrieve the annotation file corresponding to your array
Hi, thanks. One data is from chip A-GEOD-8490 - Illumina HumanMethylation27 BeadChip (HumanMethylation27_270596_v.1.2) and another one is from A-MEXP-2255 - Illumina Infinium HumanMethylation450 BeadChip. Do you have any idea of the mapping of these reads? Best, Xinhui
